20 Most Recent 2006 Buick Rainier Questions & Answers


Look for the little plastic star drive adjusters to adjust up and down. I use a very small SAE deep well socket to adjust mine 7/32" if I recall correctly. Look near the rear of the headlight assembly. That's where Trailblazers are (Same platform as Rainier), but I know the heads lights differ just a tad.

Easy fix, it's your transmission linkeage bushings. They do break because they're plastic. Dorman makes them.

Happens on rough road or bumps? Grab a hold of your sway bar links fronts and rears, should be tight, no play. These things sound like metal to metal tapping, very common. Get a replacement link that has a greaseable fitting. Easy easy DIY.

That could be a tough one to diagnose even with the proper diagnostic tools . Your best would be to take your vehicle to a qualified repair shop to have it checked ! You don't want listen to people on here saying it's this or that and just replacing parts that don't fix it . With all the electronics on your vehicle this problem could be a lot of thing's . And with out testing and knowing for sure I wouldn't even say it's one thing or another .

Most manufacturers won't provide a free service manual, just the owners manual. If you just need service details on one section of the vehicle, sometimes a dealer will copy a couple of pertinent pages from their manual just to help you out. For example, I once had a particular electrical problem and asked the dealer service department for a print-out on one or two pages of the electrical system and they had no problem doing that. Good luck.

Nothing to reset. If the compressor won't come on it's probably gone. If you ever drive your car in high water you have submerged it. They aren't cheap. Around 600.00 for parts. Labor is extra.

If this is an oem system, they are not high quality. Regardless of what you paid for it, they are no match for aftermarket. To troubleshoot this the easy way, get a meter for measuring ohms and check the coils on each speaker, if you could get a scope to see the output on the amp that would help.

You should have an EVAP leak test done . It could be a leaking purge valve , you could need a new gas cap as well or it could be the fuel filler neck . or assorted hoses or the fuel tank pressure sensor . If the check engine light is lit there will be a code .
DTC P0442: Evaporative Emissions (EVAP) System Small Leak Detected or
DTC P0455: Evaporative Emission (EVAP) System Large Leak
DTC P0446: Evaporative Emissions (EVAP) Vent System Performance
You have to jack up the vehicle , the purge valve is attached to the engine behind the A/C compressor .

Almost all relays are under the hood usually right side. There should be a chart in the cap saying what is what.

I assume that you want to see while driving, I use a suction cup backed mirror stuck to the windscreen to one side of the rear view mirror. If your child is in a rearwards facing seat you would need two mirrors one at the front and one towards the rear of the car. Hope this helps.
