2000 Regal Stalls And Start Back Up

Been having a problem with my 2000 Buick regal supercahrged. It has been dying while i am driving and when it happens it usually starts right back up.

2002 Buick Century Drivers Side Vents Blow Warm

A/C compressor, orifice tube and drier replaced about 1 year ago. The problem I have is that when you turn the ac on the cool air only comes out the 2 vents on the passenger side. The 2 vents on the drivers side have warm air blowing out. A/C is controls are set to max air and max cold on the temp control.


Service Engine Soon Light

what should be checked first service engine light cam sensor was bad replaced with ac Delco light came back on with in 10 miles took it back was told crank sensor may be bad or may have a bad pcm. He wasn't sure and didn't want to spend my money. The car is harder to start at times. It was dead once on third attempt to start it started right up rough idle. Not as much pep. Also the door locks will lock and unlock at times for no reason while in park idling. Where would be a good place to start?




Water Pump Leaking

I have a 1991 park ave. I only paid $800 for it and put a ton into it; brakes and lines, power steering pump, alternator, coil pack, ignition module, tires. Then my water pump went out. My boyfriend and I took the old one off which looked original to the car, scraped off the old gasket and cleaned it really well. We put on the new pump by following the directions that came with it. We put the belt and motor mounts back and put it all back together. But its still dripping antifreeze. Then someone told me we were supposed to use a gasket sealer around the new gasket. I really dont want to have to take it all back apart because I'm getting a new car in a few weeks. Is there anything i can seal it with from the outside?.


1998 Lesabre 3800 v6 coolant leak

Please tell me what could this possibly be??.


Problem with no dash lights on my 2003 Buick Century.

The dash panel lights are all out, except when I first start my car. Then all the warning lights will flash just for a second. Afterwards, everything goes dark. Subsequently, my tail lights don't work whenever the panel lights are out. I would be extremely grateful if you can answer this, because everyone keeps giving me the run around. I've already gotten a ticket for this, and I am a struggling mommy. I honestly would donate.


Transmission Shudders

04 Buick Lesabre shifts rough sometimes from 1st to 2nd feels like a slight shudder, been told need another transmission. Had it flushed, has helped some. Has 225 60r16 tires when door panel says 215 70r 15 tires. Some models came with the 225 option. I was wondering does or can computer shift points need to be changed, I've heard with different tires computer needs to be reset or it throws shifts, speedometer and odometer off. The flushing showed no signs of debris in the pan. Was wondering does it need an additive or do some Buick just tend to have that noticeable shift, tends to do more if I push the gas harder than normal.
