Everytime I turn my key to acc, the clock turns on and when i put it to "ON" the clock turns off, the backlighting on the cluster turns on for a brief second and then turns off and the clock shuts off and resets itself back to 1:00.

I've checked all my fuses and everything is good, I also tried another cluster and everything is good. There are no coins in the cig lighter either.

The AC unit will not power on either. I'm not sure if these are related but does anyone have any ideas>?

 

I have this EXACT same problem after a stereo guy installed my new unit. My A/C unit works fine so I think the 2 problems are unrelated. My cars at the shop right now because he is going to pay to get it fixed so I'll let you know what they come up with.

 

BTW, does your power seat and steering tilt work after put in the ON position? Or just when its on ACC and in OFF? Mine don't work after I put it to ON

 

Heard back from the car place and guess what, they have no idea. Its either take it to Lexus or I don't know what.

 

"Take it to Lexus", those words come from the devil. LOL! Sends a bad vibe through my body when I hear that.

 

I figuered out the AC unit, but now my cluster still isn't working, did you get any news?

 

I fonud some old diagrams that may be of use to you Tim. (since you are deeper into it). I'll get them scanned.

 

A ground wire was disconnected and not getting power to the gauge cluster. Dont' really know where but maybe that will help you figure out your problem.
