I just had this issue because I had not driven my car in a while and the battery started loosing it's charge.

Awesome tip, worked! I put a battery in recently and the window wasn't up. Got it to go up, but it stopped going up after closing, noticed after a rain storm and water in the floor board. Thanks!

Awesome tip! This tip worked for me after replacing my battery!

Will this also cause the door latch not to release with the buttons from time to time? I replaced the latch (old one had physical internal damage), but the using the switches works intermittently only after the car has sat for a while.

edit: I tried this and it works, but after I close the door, the driver side window will index and re-index. Had to put in a new battery. 2nd problem is the door latch won't work consistently after replacing it with a new one from gmpartsdirect.com. If I bang on the door where the red light is that blinks to show the door is locked or not, it will index and re-index. Connections are tight and I had never taken the door panel off until I found banging on it works.

Any ideas?

Your battery may be showing 14.5 volts but that is only when the engine is running. It merely means it is accepting the charging voltage the alternator is putting out. Once the car has been siting overnight check the standing voltage with a multi meter. Depending on the type of battery you have a strong battery will show 12.7 to 13.0 volts. A weak one will be in the high 11's to 12.0. Also remember that when you access the battery to test it any interior lights that are on will give you a false lower than actual reading. On my Z06 I pull the two trunk lights gently out of their location and disconnect the power feed by depressing the locking tab and pulling outward. When done testing the battery I reinstall the two lights.

Good luck.

Didn't notice how old this thread is. My bad

Dude this forum is awesome, my 2007 Z06 started doing this and within a couple minutes I checked this forum and BAM there was the answer. 30 sec later my window is fixed. Thanks!

Hey is your rad cooling fan not coming on or is the car overheating? I had a similar issues with the control module. It has 2 wire connectors right before the module and it will melt and malfunction. Quick easy fix was to cut both wires and hard wire it and remove the male/female connector. No more fan problems

This is common if you have modified your motor...

And exactly was does this have to do with the windows not going all the way up?

I was trying to reply to argeea above this post. He was working on his rad cooling problem.

Since that has nothing to do with this topic, you should have private messaged him instead.

Thanks for the heads up - you must be lonely...

Just trying to help a rookie out. FYI - I don't make the rules. There are forum rules which you should review since you seem to be completely ignorant of.
