When I purchased my 2007 GMC Yukon the passenger power seat would adjust back and forth; however, it would not adjust up and down. Thank you.

I just changed the starter as well as the fuel filter.the fuel pump turns and it starts when I put gas in the carborater but it won't stay on...

Even though I had the code erased. What else could be the problem?

Any idea what is causing this to happen? we have changed the oil the crank shaft sensor

I replaced the starter already. It's not the battery or alternates. It's not turning over.

Rear buttons won't work

I put my old brake booster back in and I even replaced the brake light sencer that hooks on to the brake bar what ever I try nothing is working.

I'm having trouble with my brake lights not working since I replaced the booster and the brake light switch. Any suggestions.

I changed my brake booster with one out of a Chevy truck and I couldn't get the shifter to come out of park unless I started the motor then turned it off just so the engine died then the shifter would move, but I had no brake lights either. I put the old booster back in to see if that was the issue but it still malfunctioned . I then replaced the brake light switch ,still no help. Can you point me in the right direction.

And my door locks constantly keep trying to lock and unlock

After an attempted theft of our 98 GMC Yukon we had to replace the whole steering column. Now because of the pass lock system the security light stays on and shuts off the ignition after a couple of seconds. Will replacing the ignition fix the problem?

Hear a banging noise when going over speed bumps or pot holes on front left. Shakes under braking, worse between 40-50 mph. And alignment off but just had it done at a shop and wheels balanced?

Noise Slows down at stops. Had the oil changed and water pump replaced. Then this tapping started. Taken to many different places no one knows.Any

suggestion? They have check transmission,fly wheel,and harmonic balancer. We are new to this area and don't know a good mechanic. But after trying 4 places still no answer. HELP!

I had a P0430 code show up about 2 weeks ago. About 4 - 5 days ago white smoke began coming out of the tailpipe. It was steam, no gas or sweet smell, and there was also water coming from the tailpipe and after I parked the car - water under the engine. I think it was water anyway. I've read that it could be transmission fluid, but when I went to check today the smoke has mostly subsided and there is no more water under the engine after I run it. The cars power has lessened, and the gears seem to be shifting late. The idle is also very slow to respond and after acceleration it returns to idle rpm's slowly. I have an Actron scanner and the following codes were generated:

The O2 sensors readings while the car was operating seemed like they were good = there was a wave like graph generated from both pre-cat sensors and a level reading for both post-cat sensors. There were times it was a bit "jumpy", but overall they were good it seemed. The fuel trim from the freeze data read:
ST FTRM11 = -3.1
ST FTRM12 = -3.1
LT FTRM11 = 4.7
LT FTRM12 = 3.1

I'm hoping someone can help me figure this out before I have to go to the shop.....which I may have to do anyway :( I'm a teacher and broke, go figure...... Thanks in advance for any help.

I'll be driving down the road and I'll have flashing stability track is I think disabled I'd have to ask my husband & the traction control is disabled engine power is reduced so the vehicle reduces speed to 40-35 mph. Has anyone else experienced this?

but wile crank back when fule is added what is making this happen and what do I need to do to fix it

twice recently, the fuel gauge has read just at a 1/4 of a tank and then dropped to empty as soon as i turn the car off. i have read of this happening in older gmc yukon models, but wondering if anyone else has experienced this problem.

raw fuel smell coming from driver's side rear whell well area. No signs of wet fuel no trouble codes.
