I have an 04 G35 Coupe and for the last few months, the window delays in going up. I click it to go up and in pop's up slightly and back down. This usually happens about 2 or 3 times and then will go up. This morning however I didn't even do that. After a few minutes I was able to get it to work. Kinda cold this morning for a window down. Any ideas what to do or what the cause. My guess the motor is getting bad on the window. Any ideas on the cost?

Your motor is bad....you can get asnwers to most questions like this by using the forum search feature under the "forum" link at the top of the page. Cost will be about $500+ dealer or $150 DIY w aftermarket motor.

 

Thanks for the info. I was afraid of that. This sight has been very helpful. I had tire issues too.
