My gas tank suddenly has become very slow to fill when refueling. I was told that it is likely a stuck tank vent valve.
Just stopped opening one day. Took it to the dealership and had disagnostic test done- showed nothing was wrong. Fuses were checked with no issues. The dealership said they would replace the entire back door locks for $500, but still couldn't guarantee that it would solve the problem. What else can i do?
Can you explain how to fix the suspension system ?
There is no temp sender on this vehicle. Is the engine temp mechanical controlled thru the BCM or PCM? All other gauges work fine and there is no CEL on. It does have the temp sensor at the front of the left head. I know a BCM replacement requires work with a TECH II scanner and online with GM and about $800 at the dealer. Thank you for any input.

Been taving problems with loss of power at certain times while driving.
I have a knocking noise at take off and as slowing down. It sounds like the rear end to me, but wanted to see if anyone had any other ideas (trans or transfer case).
I recently went to dealer to pick up a door lock actuator for the passenger side front door. It had only two electrical connections on it instead of three that is on my vehicle. The third electrical connector is for a plunger is what I was told and that he wasn't sure if it was needed. Does anyone actually know if it is needed or can I use the actuator with 2 electrical connections? Also what is the purpose of the plunger?
My 1999 yukon Denali pops and clunks when its cold and also shutters like its going to shut off, but it stops after I gun it and it warms up plus there is a smell like burning or somthing. I have greased slip yoke, removed fuses(T-Case, 4wd and cruse control fuse) trying to trace the problem. Starting to get really tried of this thing, think i may just run over it with my lifted Ford F-350. My sister had the transmission replaced about a year ago while she owned it, and thats why i cant figure out what the deal is. It throws the check engine light on, but after it smooths out the engine light goes off. Think i covered it all, please any help would be greatly appreciated. Thanks
it shut off when i shut eng down
fuse was ok
The electrical problem happens occasionally.Had the alternator replaced, still having problems.Battery is good. Yesterday the problem escalated to lights flickering, power door locks went up and down and I even loss engine acceleration for a brief moment. I keep taking it in and they can't repeat it on demand so mechanics don't know what is wrong. Help!
