Instrument Cluster and AC not working

I have an issue where the instrument cluster (tach, spedo, fuel, temp, door open indicator, etc) and AC stop working. It only happens under the following conditions and can be reproduced easily. All fuses have been check and are OK.

1.No Gauges
2.Remove and replace Multi-Fuse 20 (which is new and good)
3.Gauges and AC work
4.Drive car or start etc. and everything works fine
5.Power off car for exactly 1 min. or more with doors closed
6.Start car and no gauges or AC again
7.If wait less than 1 min. (tested 30 sec. to 59 sec. ) to restart the car and all gauges and AC continue to work fine

Looking for suggestions on where to start diagnosing. TY

Nothing yet and I have replaced the body ECU and gauge cluster and the problem still exists. I am continuing to trace and troubleshoot, but no luck yet.

Thanks for the update. I'm continuing to troubleshoot and experiment. I'd like to fix it myself, if possible. If I find anything out, I'll let you know.
Being female, I really don't want to go to the dealer... they are, unfortunately, my very last resort.

Finally gave in and took the car to Toyota dealership for service. It's been there about 7 weeks now, with over $2,000 in inventory parts that need to be returned because they tried and tested different things. It should be ready next week so I'm told. I'll keep you posted.

Took it to the dealer...even they were stumped. They finally had to replace the whole instrument cluster (couldn't get a new part so they had to install an old one). We are not electrically knowledgeable, so the dealer was our only choice. They had the car for close to 4 months.

So cabrunet, did that fix it? I'm having identical problem out of no where. Mine seems to have come on a couple times since then while driving and wrked for a couple trips after then..dead. it's funny all I gotta do is open the door and I know since the red light for a door being open doesn't illuminate... besides all that not working my reverse beep doesn't sound either, as well as my DTR lights aren't working.


I used to work for toyota so I'm hoping to get some grace rather then rack up a bill. I can get a cluster on ebay for like 100 tops. Mine is 412 with employees discount through toyota. But want to see how likley just that part fixes it all

Hillzer, before you replace your old cluster with the fried terminal, have a quick look at this post:
https://www.celicahobby.com/forums/...-dont-work-are-they-fried.html#Post86523

Its about jumping the connector, to bypass the RADIO DIMMER (IIRC) that is burnt (shorted) within your gauge cluster; preventing the entire console, radio, and gauge cluster to light up. Once the two wires within the images are connected, everything will work again, except obviously, being able to dim the radio. And everything else is still protected by the described fuse.

Thanks caffeinekid, but is that my problem? That is directly what's causing this craziness?
