I changed the window motor, regulator and switch on drivers side door. The passenger side switch works, a little slow, but does its job. Using drivers side switch, rolling both passenger and drivers side up or down doesn't always work. It works the first few tries but then quits. Then if you wait a few minutes it will work a few tries again... The cycle continues. So is it a wiring problem or what, where do I look or what are the next steps?

Changed today drove about five miles car cut off and won't start.

Downstream ak at map sensor, melted MAP sensor ground wire, fans then shut down,replaced thermostat,plugs melted off.replace the plugs. At 30Mph it was dead in the water. Got it home & pulled codes 141, 171, 300. Replaced Downstream o2 sensor,battery, engine thermal sensor (under thermostat housing). Achieved idiocracy by erasing codes and evading loop mode. Coil check acceptable , correct resistance at plug wire connection on top, continuity though no resistance on bottom of coils. No trigger signal present at ignition module w/ homemade LED tester and engine cranking over.Temp light on Comm..Makes plugged, then flooded sound when attempting to start. Found pcm in 2000 bonneville that I can have reprogrammed for $100, but have recently spent $300 + $7,000 in suspension,steering components, cabin components instruments and tires and wheels, prof. body work+ have much love into it. Is there a temp sensor capable of causing shutdown or no start, or could it be a knock sensor

do I need to pull motor

whats wrong

when I took off shift knob, there is a yellow plastic stem that is broken. without the shift knob, I press down on this stem piece and car goes into gear perfectly. so what is this plastic stem piece called and how do I replace it? thank you

After about 2-3 min my car will start surging and then die. Normal operating temp. Starts right back up. No codes, no lights come on on the dash. Have replaced the IAC valve but stilldoing it. Could the MAF OR TP sensor be bad?

My grand prix is the gtp

when the car is cold it works fine but once it warms up it misses or hesitates when accelerating to interstate speed. I get a P0300 code when accelerating to high speeds. car hesitates and miss fires.

Diagnostic test showed "Park Range Selector" fault. Sometimes I have to use the emerg button by the gear shift to get it out of park or to get my key out. If I put a load on the car like going up a hill the engine looses all power. And the "check engine" light starts blinking its usually on. Trouble code P0171 System adaptive fuel too lean. Hope this makes some since
