To reset the driver's side power window auto-close:
1. Push down and hold the driver’s door power window switch to completely open the window.
2. Pull and hold up the driver’s door power window switch until the window closes. Continue holding the switch for approximately one second until the switch changes from blinking to a constant illumination.
3. Check for proper operation of the “one–touch open/close” by pushing the switch briefly to the “DOWN” and “UP” positions.

To reset the moonroof one-touch operation:
With ignition switch in the “ON” position, do the following:
1. Push and hold the “TILT UP” side of the switch until the moon roof tilts all the way up and then tilts down slightly (approximately 10 mm [0.39 in.] at the rear).
2. Check for proper operation of the “one–touch slide open/close” and “one–touch tilt up/down” functions by pushing the switch briefly to the “SLIDE OPEN” and
“TILT UP” positions.

To reset the rear window operation:
1. Turn ignition switch to the “ON” position.
2. Push the back door power window switch to the “DOWN” side to open the window.
3. Push and hold the back door power window switch to the “UP” side until the window closes. Continue holding it for approximately 1 second.
4. Check for proper operation of the “one-touch open/close” functions by pushing the switch briefly to the “DOWN” and “UP” position.

The compass will also need to be reset if you disconnect the battery. Instructions for that are in the Owners Manual. You need to look at a map of the country to determine which zone you're in, and the instuructions are slightly different for 2003-2006 vs. 2007-2009.

At the time i didn't thought it was related to the battery being disconnected.

I took my 4R to the mechanic shop. They waste 2hrs trying and checking everything.
When i came back it worked but they had no explanation of what caused the problem and what resolved it. They said maybe something was frozen or just a bad connection.

It cost me about 180$. Problem solved but i feared it will be back sometime.

That's exactly what happened about a month later. I disconnected the battery again and the problem was back.
I then realized it has something to do with the battery disconnection... But didn't know what.
I was about to take the 4R to a good shop specialized in electric problems. I was thinking about all the $$$ going out of my pockets again and i took a chance... What about a little Google search on that problem?

That's what i did and i just found this post and saying to myself "I couldn't be just that?". I ran to my 4R and followed the rear window reset instructions and guess what?

PROBLEM SOLVED! It only took 30 secs! You made my day!

You just saved me some $$$. I can't believe professionnals didn't find that, and that i paid 180$ for nothing...

This forum will be a must from now on...


Thanks again!
