Sometimes the glass will stick to the rubber weatherstripping when the windows are not used for a long time. We have that problem on our 2005 Town & Country, between air conditioning in summer and heating in winter, we rarely use the windows. Try to make a habit of dropping all the windows slightly (an inch or two is enough, just to move the glass) each time you get in the car, or at least once a week. Sometimes just opening and closing the door a few times jars the window enough to break it loose.

If that does not fix it, you may have a bad switch or motor.

Testimonial: "Most likely as you suggested, the window was stuck to the rubber gasket as we've had prolonged period of weather 100+. I thought the lock was on."

Problem with idle speed. The idle is controlled by the pcm (engine computer) through the operation of the Idle Air Control valve or motor. But several other sensors are also at work, like the throttle position sensor, the coolant temperature sensor, the MAP sensor or the Mass Air Flow sensor. The computer monitors all engine conditions to optimize performance and driveability-this includes keeping idle speed correct.
Would probably help you if you could see what all those sensors are telling the pcm-so you need a scanner capable of giving live stream data. And don't forget, your '94 is OBD-1, not OBD-II like all cars since 1996 on have. A garage should have such capable scanners, but they are kind of high end, not your typical cheap code scanner.

99 grand prix gt window regulator?


Noises are deceptive at best.

Until you pull the door panel you really can't be sure what it is.

It could be a rusted rail or the window fell off the rail , or, or,o or..you have one of them look and hunt problems.

Most window issues are easily fixed if you have the slightest mechanical apptitude, it won't be that hard.

I hope this helps you some

pull the door panels off and remove the plastic sound deadenning liner from the door. find the window motor and unplug the wire harness. check the voltage by ressing down as to open the window(you can do up too, same thing), and see if you get 12volts when you press the button. if so your motors are burned. if not you have power issues and need to check your fuses. start off with the fuses first.

Change the switch with another switch to see if the one you had was bad. If it the switch is good, then the motor is bad. You will have to pull all screws out of door panel, pry off panel, and access motor. You may need to drill the rivets to access motor.

Burning oil, but dont know why


Nowdays 1 Qt. in 3000 miles, really isn't that bad, even some new vehicles claim that's normal. I know with my current vehicles, both at approx. 150,000-160,000 miles, they won't use any for first while after an oil change, but then after mileage starts adding up again, they start to use a little, approx.I Qt, every 1000 miles or so, until it's changed again. I've switched to the high mileage oil, just for piece of mind, as they say it revives seals, and has added protection for the higher mileage engines.This time around I'm thinking of adding "Lucas" & see how it works, as I've heard some pretty good reports on it, just to see if it will prolong that oil breakdown, at mid change.
