My car windows only work when it's cold outside

All the windows work off one circuit breaker, there isn't a relay for them. So if one works, they all have power. Replace the window regulator and motor inside the door.

Usually the Cause to that is the windshield on the passenger side closest to the hood has a bad seal and is leaking into the motor.. In turn when u turn on the motor it splashes water on the resistor.. get some clear window sealant repair.. not the silicone.. But sealant. Do the bottom of the windsheild where the glass meets the plastic.. You will see when looking close on the passenger side its not seated close enough to the window.. It separates and causes it to leak.. hope it helped u

yes its passenger side on most cars ,check for a feed to it first though

does this car have a trailer hitch? if so, check the hitch wires for damage or a short

with winter being here you might want to consider having a new thermostat put in to increase the heat in side,but make sure your radiator is full when engine is cold

Sounds like it could be the actual switch for the windows with could be an easy fix if U know how to remove the switch from the door.

Hope this helps

GM cars have a window regulator that is made of a cable and plastic gears. They wear out and windows quit working. The new unit comes with regulator and new motor. This is a common problem on gm cars. These regulators are around $250 each. I would search junk yards, or look on ebay they sell aftermarket for around $80.00

Turn off the car before pulling out a fuse. Find the two fuse boxes in the passenger compartment of your Oldsmobile Alero. One is on the driver's side and the other is on the passenger's side of the instrument panel.
Consult your owner's manual to find the location of the fuse you need to change. You can also find this information on the inside of the fuse box cover.

Locate the blown fuse. If it's a radio fuse in a 2000 Oldsmobile Alero, you'd find it in the slot marked "Radio Batt" in the fuse box on the passenger's side. Use the fuse puller inside of the fuse box to remove the fuse.

Check the inside wire of the fuse. A blown fuse has a burned or broken wire.

Put in a new fuse with the same rating. Verify the fuse rating against what's listed on the fuse box or owner's manual for the particular model and year in question. Click it into place and close the fuse cover. Restart you car and verify you've corrected the problem.

If the radio calls for a code: If you bought the car new then there should be writen in the manual the code for the theft lock system on the radio. Pre-owned then it might ,might not be in there. or if you don't have one at all. 
Go to your nearest GM dealer and have them fix it by finding the code using the Vin #. Make sure to have them write it down for you in case this happens again. 

Good luck and hope this helps

Their is a separate motor for each window. The least expensive fix is to replace the entire track assembly and motor. This is not a big job if you have done it before but it could be if you are not mechanical.

I would be very suspicious of the drivers master swich. If the window works fine on the other side it's an easy assumption that the window motor and regulator are operative. The switches are usually fairly inexpensive (less then 100.00 ) and easy to install
