#1880 of 2196 Re: How do i change the rear 3 spark plugs? [dounojc] by mcclearyb Nov 06, 2007 (8:38 am)
Replying to: dounojc (Nov 02, 2007 8:19 am) I just replaced the spark plugs on my '03 RDV CXL. The trick is to remove the plugs from underneath the vehicle. Before you start, make sure the engine is cold. If the engine is hot/warm, you will burn your arm and could damage the spark plug threads.   Jack the vehicle up, crawl underneath and access the rear plugs by sticking your hand up next to exhaust pipe. Since your hand will be in the vicinity of the oxygen sensor, be careful not to damage the oxygen sensor wires. Next, twist the spark plug boot to loosen it before removal. I used spark plug boot pliers (OEM #25542) I picked up at AutoZone to remove the boots. Try to clean the spark plug recess area as best you can with compressed air before removing the plug. Then, use a flex-head ratchet with a long handle to remove the old plug. I used a Craftsman #42794 fine-tooth ratchet with a 5/8" spark plug socket on a 3-inch extension. When installing the new plug, hand tighten the plug with the socket and extension first before tightening 1/16" turn with the ratchet. Be careful when tightening the plug since the cylinder heads are aluminum. The service manual says to tighten the plugs 15 N-m (11 ft-lb), but good luck getting a torque wrench in there.   Note that the service manual has you take the top engine struts off and rotate the engine forward to access the rear plugs. I tried this, but still could not access the rear plugs from the top.

Our car is at dealer and mechanic can't understand what is causing our mirrors to move while the car's motor is turned off. First the passenger mirror began acting up, moving back and forth and making a noise until someone noticed it and came into a restaurant to tell us about it and then three weeks later the driver side mirror did the same thing. We are concerned that we may park it at night and have a dead battery the next morning. When we started the car both times the mirror "settled down". Also, from time to time the gas gauge goes a little crazy but eventually quits and is okay. The mechanic says if we can find any info on the mirrors it would help as they have never had the problem before with the rendezvousand of course, they can't get the mirrors to do anything. Any suggestions? They will have the car until Fri. evening. Replies to this message: jablonsa (Nov 09, 2007 5:45 am)

#1883 of 2196 weird stuff happening by hammering Nov 19, 2007 (8:32 pm)
When I try to start the car, it makes a strange noise and the gauges and messages flash and click on and off. Sometimes the car starts, and sometimes it acts like a bad battery. I replaced the battery and it still does it. The clock on the radio occasionally resets to 12:00 after turning the key back on. A few days ago, it stalled in traffic with the overheating message coming on. The temp gauge went way up to hot then back down to normal within seconds. Any ideas or similarities? It's a 2003. Also have ABS and AWD lights on when I hit bumps.

Replying to: hammering (Nov 19, 2007 8:32 pm) Sounds like battery cable connection problem, either corroded or broken. If it turns over slowly I would tend to suspect connection at battery. If it turns over ok but has trouble starting, I would look at connection to underhood fuse box (loose or corroded). For the ABS and AWD warning lights, I would try to correct the other electrical problem first to see if they go away then if they don't I would be looking at connections to wheel sensors for loose/ corroded/ or broken wires. If you were to get it scanned for those light, it will most likely point to sensor problem and first suggestion would be to replace hub assembly, but I would really be taking a close look at wiring first.

Replying to: ray80 (Nov 20, 2007 4:27 am) It wouldn't be the body control module like everyone else is talking about? Replies to this message: ray80 (Nov 20, 2007 7:33 am)

Replying to: hammering (Nov 20, 2007 6:54 am) Well it could be, but from what you are describing it doesn't sound like it to me. For one thing the BCM doesn't have any direct connection to starting vehicle.   Oh, and for the overheating trouble the fact that it did stall would make me think it was really hot (not false indicaters), perhaps the thermostat got stuck closed for a bit.
#1887 of 2196 Re: Engine stall [cruzak] by whattheheck Nov 21, 2007 (3:37 am)
Replying to: cruzak (Sep 26, 2007 11:22 am) I also have an 05 RDV I have the same problem with mine stalling or completely dying when coming to a slow speed or making a slow turn .I've taken my to the dealer 3 or 4 times thay cant find any codes or have no Idea what is wrong with it. I loose all power it just dies on me that is a very bad safety hazard because I had a semi behind me at one time when I was turning it was all i could do to try and steer it out of the way,thank goodness it was a slope that i had turned onto,and no one got hurt it was early morning traffic.The dealer does not think that mine is the ignition they have no idea.I told them that if I have a wreck because of this the blame would be put on their shoulders.Mind dosent do it every day it just happens out of the blue with no warning.Im scared to death everytime i get into : it ive had mine for 1 1/2 yrs. now.needless to say i want to trade it in but i dont want the next person to have this problem, I would like to know if anyone else is having this problem
#1888 of 2196 jack stand by cruzak Nov 22, 2007 (1:32 am)

#1889 of 2196 2002 Buick AWD Thumping by kristers Dec 06, 2007 (8:41 am)
I recently purchased a 2002 Buick Rendezvous CX AWD. Now that it is getting colder, it has started making a small thumping noise (seemingly from the front passenger side). It happened once when I started it (I think) and a few times when I put it into gear.   I'm not too familiar with AWD vehicles, so my question is... is this the sound an AWD makes as it locks the hubs (does it lock the hubs)? Or, is this something worse?   Thanks! Replies to this message: ray80 (Dec 06, 2007 9:56 am) kristers (Dec 06, 2007 10:34 am) exhausted (Dec 07, 2007 7:36 pm)
