I have a 1999 pontiac grand prix the window will not go up ? I have juice to the motor when i push the switch in the down position but nothing in the up. Do you think a switch or may be the motor?

there is no adjustment when changing a window motor or switch.

to fix this you have to get the whole window regulator i have a 2000 grand Prix that had the same problem .ebay is the cheapest place to find a new one ,the dealer is a couple of hundred dollars,ebay was 65 bucks

Follow the buzzing noise,to find the relay module,it is the problem

put key in and then turn to acc position then push the little pin in and it will pull out

This sucks when it happens, I have 2 grand prix and have had this happened a few times, First, if you need to get it up RIGHT NOW! This instant even if its late at night? Well its do able. You can remove the paneling, dis engage the motor and prop it up. You might have to cut a piece of wood to hold it up temporarily so that someone wont break in and steal stuff. If you just need a fix it solution, there are a few possibilities, the first thing i would recommend would be to check the window switch, they tend to go bad often. You can do this by 2 ways, One? buy a new one, or 2 get a second grand prix switch from a friend or a neighbor or from someone else and plug it in. If this works, just replace the switch, if it doesnt, then remove the door paneling, and place electricity on one of the connectors on the motor (dont worry which side as they both receive electricity when going up or down) if this works, its a faulty switch, if it doesnt, it might be (95% sure) the motor itself.

First remove the paneling (of the door) apply electricity to the motor, it doesnt matter to witch side as they both will carry power from one time to another, if that works, try checking the main switch on the driver side door, if you can get a friend to loan you his while you check or you might have to buy one. Its either the main switch or the passengers side switch if the window goes up when direct juice is applied to it.

what I would recommend is that you will have to test the window actuator first. You will need to remove the door panel to get at the actuator. From there, just jump the actuator to see if the window goes up or down. Don't worry about which terminal is positive or negative, they are switched back and forth by the control switches.

you have to remove the door panel to do so. once off, unplug the window motor and put a volt meter on the plug that plugs into the motor, not the motor itself. push the up/down button and if you get about 12 volts, if you do then your motor needs to be replaced. if not then the problem is prbably the main control switch on the drivers door. You have to remove the motor in order to get that window up or else it won't budge.

IF THE MOTOR IS STILL FINE A ON TRACK IT HAS TO BE ELEC. SO PUSH THE UP SWITCH VERY FAST ALOT OF TIMES TO SEE IF IT GETS A CONNECTION. IF SOAND IT MOVES ITS THE SWITCH IF NOT YOU ARE GOING TO HAVE TO GET TO THE MOTOR PULL PLUG OFF PUSH SWITCH AND SEE IF IT IS GETTING ELEC THERE
