Buick back up sensors by tablescape

I went to pick up my Rendezous and get my money back and the service dept asked to keep a few more days, they took the bumper off a used Rendezous in the lot and attached it to my sensor module and then it worked so they removed all the sensors in the used bumper put them in mine and for now it is working.

P0741 Code by ragerrl
May 12, 2009 (8:31 am)

I have a check Engine Light and when I brought it in they said it was a P0741 code. Basically they said they need to bring it into the transmission shop and it would cost anywhere from $600-$2000 depending on what they had to do. It shifts fine through all gears and reverse. The only problem is that it won't go into overdrive. I guess this code says that the Torque Converter Clutch is slipping. Anyways has anyone else had this problem. What are the odds that it is the selenoid???
Thanks in advance!!!

not sure if this is what you are looking for. i did the passenger side clips lsat year, and have just ordered another set for the driver side
 
The below was posted a while ago, if you can find the post it'll have pictures...
 
Buick Rendezvous (and maybe Pontiac Aztek) Window Regulator Clip Replacement $40 total!!!
 
After having our driver window stop working 4 months after buying our Rendezvous and the dealer wanting $275 for the whole motor/regulator/clip assembly I decided to look around for a replacement. Car-part.com led me to 3 different salvage yards, all telling me the same thing as the dealer, the clips cannot be purchased separately but they would be glad to sell me the whole setup for $100.
I said ok 3 times....
The first salvage yard called me after i placed the order and said they had broke the clips removing it from the door.
The second salvage yard could not find the door....ya, it disappeared! the whole door!
The third was going to be the charm, after a week I called them and they said they had broke the clips also.
I was content with the door panel off and my 1x4 with a notch holding the window up....but the boss said she didnt want to drive a ghetto vehicle.
Then 3 weeks ago the passenger door clips broke! Talk about a total POS design flaw.
So internet searching led me to the Buick forums where I found the part numbers for the clips.
I ended up spending $80.45 for 4 clips, (2 for each door), shipped to my house
Since my clips were broke in about 12 pieces I had no idea how to replace them....but about an hour later both side were done.
Here are some pictures to help the next person with this project (and probably me again before its paid off)
Part numbers and references at bottom of page
 
Here is the passenger side regulator removed from the door....I think about 5 10mm bolts held it on.
 
Here is the small "barrel" that snaps into the clip and moves it up and down the window.
 
The clip slides on the track first
 
Then slide the clip over the regulator and lock it in place (you can kind of notice the slot for the barrel)
 
Once the clip is locked on, line up the barrel and push it in with a screwdriver
 
The barrel is locked in place
 
Driver side ready
 
So your ready to try it yourself? I would say most people with a little brain can do this with no problem.
The clips can be found at gmpartsdirect.com
The left part number is #15286776 and the right is #15286777
 
Thanks to the guys (and gals) at http://townhall-talk.edmunds.com

Possible fuel pump issue by dabacon
May 12, 2009 (10:56 am)
Reply
After a check engine soon light appeared in my 2003 Rendezvous, I was told that it had a fault code of P0453 which had to do with an evap emission control system pressure sensor having a high input. I took the car to another local servicer and they are saying that the fuel pump needs to be replaced along with all sorts of other parts involved with the pump. It would cost over $850 to do all that. Is this correct? Is this really another issue and not the pump at all?

dabacon,
Unless your car was having problems starting, stalling, or not having power, there's no reason to believe you need a fuel pump. You do NOT need a new fuel pump for a P0453 code - it's a vapor system code completely unrelated to the fuel delivery system. I used work in the group that made fuel pumps for Ford and analyzed thousands of warranty claims. A fuel pump repair can be costly. The part itself is not cheap, and the labor to do it requires draining and dropping the fuel tank. $850 is in the ballpark but seems high. I would ask for a breakdown on the repair to see what is involved.

I thought about this some more, and there is one legitimate reason to replace a fuel delivery module for a P0453 code. IF the fuel tank truly does have high pressure and IF there is a valve in the flange of the fuel delivery module to vent vapor and IF that is the highest vapor valve on the fuel tank and IF that valve is stuck shut, then replacing the fuel delivery module could be appropriate to allow your tank to vent. I haven't seen the Rendezvous tank to know for sure, but I would say this is a real long shot. If the P0453 code ever sets with less than a 7/8 tank of fuel, this is not the problem because one of the other valves on the tank should be venting.

I appreciate your advice and expertise. I had a dealer look at the problem as well. They stated that water leaking from the air conditioner had gotten on to the fuel pump and the wiring and connectors around it, rusting and corroding them. However the fuel pump itself should be ok they said. The dealers wanted even more money for the repairs and said that the pump could lose pressure and the car not start or just stop running while driving. However they said that could happen tomorrow or two years from now. After they reset the P0453 code, the check engine light has not come back on. I live in a very arid area, but had just left a pretty humid area the day that the light came on. Some of your assumptions have already proven to be true it seems, but I still don't know if replacing everything is necessary at this time. The replacing-part-by-mileage section of the owner’s manual never said anything about having to replace the pump. However, with the water leaking it may have done enough to warrant that. I probably need one more opinion now about the extent of the water damage on the pump (and get an extension for the tube where the water leaks out so it can go directly to the ground). I've been driving it for 2 weeks now with no problems

The fuel pump is located INSIDE of the fuel tank, so there is no way water dripping would affect the pump itself at all.
 
There is an electrical connector (C305) located under the car almost under the drivers seat. This connector has numerous wires, one of which supplies power to the fuel pump. Some owners have had mosture, salt spray, etc get into those connections and cause problems.
 
A few owners that had stalling, no start, engine shut off as if the key were turned off, etc traced their problems to the connector C305. Try an internet search for the C305. Perhaps this is what the mechanic is talking about.
 
 I doubt if the AC condensation would be able to travel that far and get into the connection. I think the vent tube is on the passenger side, not the drivers side.

02 BCM Issues by glesser

Hey All. Purchased an 2002 Cx Vous about 2 years ago and have not had any issues until now. Recently I got into car went to start it and got the Pass Key error - where the radio locked up, and the error for PK3 showed up on the dash. I was not able to pop the back trunk or roll the windows down. I shut the truck off - gave it a few minutes, and everything was fine - except the radio says CALIBRATE. I have been driving with this issue for about 2 weeks now - but it seems to be a little more severe. Examples - daytime running lights will not shut off, or interior lights will not shut off when truck is off. Some times when pressing the LOCK on the FOB - it locks the doors, and then the horn does not honk. Sometimes when the truck is off, everything looks good, the windows still go down even after I open the door. I had the ODB scan tool take a look at the truck and it said P0141 - bad O2 sensor - so I know I have to replace that for sure, but no other errors came up. I have followed up with every possible forum to see what I could do and I tried the uplug battery option, and it fixes the issue sometimes for 8 - 10 starts and others it only fixes it for one start. I called the local GM dealership here in London Ontario and was advised it is a definate BCM issue. COST 220 for them to scan the codes, 899 for a new BCM and 110 an hour for labour - with a minimum 4 hours work. Before I go and pay thru the teeth on this one - can any one help me out? is it the BCM? Am I being ripped off in the cost department. Any and all information would be greatly appreciated, as pulling the positive every night is starting to take its toll.
