#110 of 312 A/C. Electrical, & hesitation
Jun 11, 2010 (5:46 pm)
I have a 2004 Buick Rainier that has numerous problems. I have read lots of posts about the electrical problems with speed odometer, mine is not working at all!! With all the problems, I can't understand why Buick does not have a recall in regards to this issue. In regards to the A/C unit, my front vents do not blow any air. It will only flow from the vents at my feet. Does anyone else have this problem, and what were the repair costs? Another ongoing problem is hesitation on acceleration. This has been going on for months. I have taken it to several auto repair places, one said to replace the fuel filter, I did, problem not solved. Another repair place suggested that I flush the transmission and get a tune up, no luck there either. I have had numerous problems with this car and have spent several thousand dollars on repairs. This is the worse car I have ever owned!!!! Any one else with similar problems, especially with the hesitation on acceleration, please let me know. I need suggestions!!! Thanks

I have a 2004 Rainer with about 70,000 miles.
I have a very similar problem with the AC. It will not blow out of the chest level vents but will blow out of the floor and defrost vents. It also causes the engine RPM's to drop and nearly die when idling at a standstill.
Any idea what the problem is? I'd like to know if it is a simple fix.

I had one person look at it and told me I needed an actuator, apparently there are 4 on the car. I had a tune up done and after it was done the air was not blowing out of the front vents. They agreed to repair my car for free, because I feel they did something to the air, it was working fine when I took the car in. They replaced one actuator and told me it blew the other one out when they put the one in. So, they would not repair my car. I have no idea what it will cost to repair it.. I have noticed that the car idles, and it actually cut off on me one day when I had the air on and was sitting still.. So now I mostly ride around without the air on and its nearly 100 here in Columbia, SC. Yesterday my rear view mirror came loose and had to repair it myself. This car has been a constant problem over the last year and I wonder what will happen next. My neighbor has the same vehicle and her speedodometer does not work either..

".....I have noticed that the car idles, and it actually cut off on me one day when I had the air on and was sitting still.. "
While no expert, I would have the actuator replaced. If it is blown, it may be causing a vaccuum leak which will cause the engine to run a little rough, and can cause it to stall.
As for the speedo, the entire instrument cluster is one unit. Check electronic shops in your area to see if the can repair them. I had this happen to a 1988 Regal. The dealer wanted $350 for a remanufactured unit, local boneyards wanted $250 for a used one w/ no guarantee. When I pulled the unit out myself (I was going to have a friend look at it) there was a sticker on it for a electronic company. I called them, they told me $149 to refurbish it. Another $20 to ship it to them, and problem solved. I posted the name on another post here for the Rainier, but not sure if it got removed as SPAM.
#114 of 312 A/C Doesn't Want To Cool Fast Enough
Jul 25, 2010 (11:31 am)
It's about 100 degrees here and getting into my 2005 Buick Rainier is not a pleasant experience. We turn the A/C on and it blows hot air. It has to run for quite a while to get it to cool, but once it does decide to cool, it's cold. I read in another post the following..." If it sits for less than 4 hours and the temperature increases by less than 20 degrees you have to run it at a steady speed for a few miles/minutes for it to recognize that the increase in temperature at the sensor is real and not caused by the sun shining on the vehicle." Sometimes this is over 5 minutes. So if my A/C temp wasn't managed by a computer, I would be cool. How do I override this?

Hey Iceman, My Buick Rainier did the same thing I changed the cam sensor and crank senor and it still idled rough and would stall. So for giggles I changed the fuel filter and what would you know it runs normal again. You will need to have the check engine light reset though other wise it will still say bad cam and crank sensor. I hope this fixes your problem as well. good luck.

I was told by a mechanic to watch the fuel filter, to change it every 4 oil changes the whole fuel system is very touchy and will cause the engine light to come on and say you may have a faulty sensor which in some cases you may but start with fuel filter first its only $16.00, also when doing routine maintenance its always good to inspect the brake pads and rotors, also he told me that the Rainier is known for going threw front wheel bearings ,I have just replaced my rotors and bearings and I have had my Rainier for 1 yr. But it also has 96000 miles on it. I am not sure how many times the first owner changed it.
#119 of 312 dangerous fuel gauge readings
Sep 07, 2010 (5:22 pm)
My '05 Rainier just started having strange and disturbing problems within the past month. The fuel gauge registers E when it shouldn't, and always after I've just filled up. Warning light comes on along with the DIC low fuel msg. At other times, the gauge just bounces around. Thank God I haven't been stranded yet because I avoid driving whenever possible and don't let the tank get low. In searching for info, I've discovered this is a common problem with all the sister SUV's (Envoy, Trailblazer, etc.) of this age. Although out of warranty, it only has 47,000 miles. There are thousands of complaints about this identical problem. Seems the fuel level sensor is the culprit (along with instrument panel problems) and that the Trailblazer owners have been quite vocal about it for years. Probably because there are (or were) so many more of them. Sometimes the check engine light comes on too and on rare occasions, the DIC completely blacks out. Seems that there has been no recall and many owners have had to shell out a lot of money to fix what appears to be a case of faulty parts. I don't think I should have to pay for this repair.
I'd like to add that I'm a middle aged woman who for the 1st time ever, intentionally sought a GM product to maybe help save jobs there. Buick seemed to have the best reputation I could afford at GM. I need reliable transportation and thought that coughing up the extra money for this vehicle would buy me that. I plan to push this issue for some resolution. It is implausible that the service dept. at the largest GM dealership in Hickory, NC didn't acknowledge this common problem when I called them today, but seems that NHTSA has received lots of complaints. Since Mariah from GM customer service regularly monitors this site, my vin# is 5GADT13S352177361 and I shouldn't have to pay to diagnose what you already know, the fuel level sensor is bad...and the instrument cluster is going soon!
