#18177 of 18274 Re: How do I turn on the reading, dome, and vanity lights on my Buick Rainier? [buickrain] by floep Sep 22, 2008 (9:01 am)
Replying to: buickrain (Sep 22, 2008 4:32 am) Your description is accurate and I understand the problem and it all points to 1 fuse of the two feeding these circuits, is dead. My problem is: I misled you, it is fuse 4 and 40 not 41, both are in the rear fuse block under the left back seat. If you still have problem between the checking procedure of the last message and this one I refer you to the service manual Vol3 page 8-544, 8-545 or 546, depending on wether it is a short or long wheelbase. the wiring runs in the roof liner down the left "B"pillar to the floor and to the fuse block. There is there a "body control module" [BCM] it could be defective, but not lightly. FLOEP

#18179 of 18274 electrical issues by chevygirlsept Nov 14, 2008 (12:33 pm)
here's a doozy for anyone who is an electrical genius and can figure out what really ails my truck:   Here are the issues: 1) lights have gone out while driving during the night (this has happened 2 times) I put my flashers on then fiddled a little with the ignition and after about a minute they came back on   2) Sometimes the car desn't want to turn over it grinds 3 revolutions graoning and moaning then kick on...sometimes I have to resatt then kicks over ok. Thia has happened about 6 times   3) Stalled at a red light. 1 time   4) "no air bag" light comes light comes on. 2 times   5)" get engine checked" light always on. Depending on whether I'm hauling a trailer it is intermitten   6) Battery light came on the a message about no charge getting to the battery. That went away after I jiggled and fiddled with the wires.   7) Today I put the air on 74 degrees and blew the fan on hight for about 8 minutes...then turned the fan way down to lo and as I accelarated the fan blower went from lo to high depending on the rpms and as I accelerated the sound was louder than normal. Usually I hardly here my car running. The blower issue went away when I turned the air off.   8) The other day I noticed that all the little buttons on my steering wheel were burning hot.   Any ideas as to what might be ailing my Trailblazer? It's an 03' straight 6 and I replaced the alternator 2 years ago and the battery 6 months ago (3rd one) And I live in South Florida... Replies to this message: brads321 (Jan 27, 2009 10:57 pm)

#18181 of 18274 Trailblazer sits lower on right side. by uschevydriver Nov 26, 2008 (4:56 pm)
I have a 2002 Trailblazer which I bought new. I noticed a few years ago that it sits lower on the right side by about 3/4 inch. I have had it checked by the dealership and they can not find any problems. They had no good explanation for it. Has anyone else had this issue? Thanks.

Replying to: uschevydriver (Nov 26, 2008 4:56 pm) If you have the auto level ride have the dealer (or another dealer) check the pressures in the air lift system they should match or be real close---I had this problem with my Rainier---the dealer found a difference and replaced something on the system and it corrected the problem---sorry but I do not recall what they replaced

Replying to: uschevydriver (Nov 26, 2008 4:56 pm) If you go back to message 15029, there are several messages regarding this problem, including what I did to correct mine on message 15071.   This assumes you have the load leveling suspension.
#18184 of 18274 No power anywhere by jay1480 Dec 14, 2008 (4:12 pm)
I have a 2004 Buick Rainier that I fried the battery on. I bought a new battery and the car now starts but all I have are my headlights. Every light or power controlled device inside or out now does not work. Is there a main fuse that I blew or do I have to check all 110 fuses? -Jason Replies to this message: floep (Dec 14, 2008 4:51 pm)

Replying to: jay1480 (Dec 14, 2008 4:12 pm) It would help [not being able to see, or hands on] to tell how you fried a battery. First of I would suggest the 125a. fuse #48 underhood fuse box.It would give approx the symptoms described. If you want more accurate answer, give more details, how did you fry it, where did it stink, what works and what does not. Floep
