Couples months ago I had an electrical tourble with my gage, the Alternator batteries gage was reduicing down to 5 amp, the lights were flashing exterior + the dash board. After a scan at Dealer, It appear that my air pump causing this, so I did change the air pump in december 2007. 18 months after (03/2008) same trouble, I did change the pump a second time, 2 weeks after same trouble, Dealer says Buick Rainier has 2 air pump under the hood, nothing to do with the air compressor in the back for the suspension, and the second one is defective also, it's about 600$ each time - Is someone has a solution for me or did someone experimented this trouble ?
#16 of 38 Erratic speedo behaviour
Apr 22, 2008 (4:42 pm)
I just bought a 2004 Rainier which has the much-read-about Speedo problem. Sometimes the speedo needle sits below zero at start-up, which always means it won't move at all when driving. Other times it is perfectly normal. Is it a sensor? Is it a cluster? Can it be corrected easily?

Our 04 Ranier started having electrical issues about 2 months ago. We had left it parked for 6 days at the airport. Started it up and none of the gauges were functioning. They may operate each time for a day, but then may go several days without working. About 3 weeks ago while driving about 15 mph, the accelerator failed to respond and the tach was locked in at 1000 rpm. After pulling over and restarting, all was well. In the past 10 days, the speedometer and tach have started failing also. Just last night, nothing was working and then it came on while driving. It did that several times.
I've checked fused and wire bundle connections but have not been able to find any problem.

My problem was solved by having the garage replace a stepper motor. Now I get smooth speedo needle movement, rather than the eratic, twitchy movements I was getting.
Your problem sounds more serious than a simple stepper motor change. I wonder if the whole cluster is in need of changing.

I also had the problem with flickering headlights on my '04 Rainier. The problem started about 6 months after I got it. I had the truck in the shop 3X for service of this problem, and even had copies of this thread documenting other owners flickering lights but the dealer denied their was a problem. When I bought a new battery after about 3 yrs, that seemed to help, but only temporary, the flickering returned. I returned the Rainier back to GM after my 48 month lease was up.
PS. I also hated the automatic climate controls, especially on the windshield defrost setting. It was impossible to adjust the temp, either too hot or too cold.

Im having a problem with my 05' Rainier.
The Gas Gauge seems to malfunction. When I fill up the tank to full it will read that it is empty and will continue to fluctuate up and down. This happened a month after I bought it from the dealer and now I am stationed overseas and cant ship my car to my station until this problem is fixed. Anyone else have this problem and know how much it cost them??

I have had problems with my speedometer racing ahead and freezing at over 100 mph. I have to start the ignition and turn it off several times to get it to go back to 0. This week it is dead, will not move off below 0 mph. I have also had instances when the radio will not function. When the motor is turned off and started, it may began to work normally again. I am very sorry I bought this vehicle. GracemontGirl

I had the speedo(instrument cluster) replaced on my 2004 Ranier. They charge
$700 plus a $900 core charge for the old one. Fortunately, I had purchased an aftermarket warranty on this car, so I had to pay only a $100 deductible. Its ridiculous that GM does'nt give any better warranty coverage than 36 months, This was an expensive car. I believe perhaps mid thirties when new. I'm pretty much done with GM and Detroit too. My wifes Subaru had the same aftermarket warranty. We've had it for over five years now and have had zero claims. nothing but normal wear items. It was way cheaper and older when purchased too.
