Hi.

Hope someone here got some experience to spare on the issue I'm about to describe.

My car is an Evo 7 EDM GSR. All windows have one touch function.

I was changing the hot/cold control cable and had to disconnect both electrical connectors on the HVAC control unit - by mistake I did it with the key on ON/ACC position. Still, hear no noises, no fires, etc.

After reassembling the dash I went to a drive and found out that both front windows weren't working. Pressing up or down made them click just like they were on the top or bottom end, but they never moved. Rear windows still work just fine.

Things I already done:

1- Installed the ETACS and drivers door control unit from another perfectly working Evo 7. Nothing changed. Reinstalled the ETACS and control unit on the "donor car" and it just worked as expected;
2- Tested ALL fuses. Not a single one blown;
3- Tested all relays. Couldn't find any problem. This was kinda nonsense since the same fuses and relays power all windows;
4- Measured voltage at the drivers door connector, close to the driver's foot rest.
12.2V - Stand by 12.2V
12.0V - Operating any rear window
11.4V - operating front passenger window - clicks but won't move
11.0V - Operating front driver window - clicks but won't move
5- When touching the front driver window motor I can feel it clicking.


This is odd. I am asking for help because I am completely out of ideas.

 

Nevermind.

Both windows just got stuck on the upper position due to non usage. Just had to take the motors out and lube the rails.
