Anyone seen this one?
When I push the "TEMP-Push" Auto button - Nothing on the Temp Contol panel excpet the yellow backlight - no temperature number; no mode icons - nothing?
And nothing works - A/C, heat, fans.
Can't see anything amiss in the Fuse-Relay box but I'm not really sure what to look for there.

Any ideas?

Did you ever figure anything out>?

I am having the same issue. The climate control unit lights up, but no fan, no heat, no nothing turns on. Radio works fine.

Can anyone please give me some tips on this matter?

Never mind my question.

Answer: Most likely the cig. lighter fuse is blown due to it being shorted because someone dropped a coin in there.

Or make sure the fuse is getting a good connection. It's located in the kickpanel.

This is for sure a fuse problem...It's a blue 15 amp fuse FYI.

This helped me out!!!!! Thank You All!!!!! It was the cig fuse.

Helped me out too! I found a dime in my cig lighter.

Can anyone please help? I have the same problem. Just bought the car from my friend and the climate control is not working. Just the back light, lights up and I am positive the cig 15 amp fuse is not bad nor the panel 7.5 amp fuse and there is nothing in the cig lighter POSITIVE.

try tweaking the fuse pins away from each other, then putting it back in.

Will try to pry the pins back into place. But I still don't think that will work. Tested the back of the climate control and the cig lighter with a ohmmeter and got both proper voltage rating and continuity. Have a feeling the problem lies within the junction block behind the dash where the wires from the cig lighter meets up with the climate control at junction block 3. Will post whatever I discover.
