Default Please help anyone have temp control issues

My 2002 corvette with the dual zone heat/air on the passenger side is not working. The dial that changes the temp when you rotate it does not move the degrees. Also the a/c light stays on when the heat/air is on even after I push the botton to turn it off. Dealer says the entire unit needs replacing for a cost of 700.00. Does anyone have any info on this. Drivers side works great, thanks, Steve.

Passenger side does nothing but change the temp on the passenger side a few degrees-stupid option.

Passenger side has no display/indication when the **** is turned.

It really does control that side.

Also, depending on the temp, the A/C light will not go off if you have the "AUTO" button pushed. Also, it won't go off if the Defrost is on.

I always found the climate control in the C5 to be a bit cumbersome...I now just leave the air off and drive fast with the top off to get cooled down, lol (joking)

Thank you for this thread. I was ready to replace my climate control unit because I thought it was bad since the passenger side **** seems to be useless. Well, it is useless, but it seems to be performing its useless function as intended.

I've had other multi-zone vehicles that actually did something, so this kinda confused me.

You can pull AND REINSERT fuse #27 in the passanger footwell so the A/C can reset and this usually does the trick. It's done a few times in my 98.

If the fuse thing dont work, you may have a passenger side actuator issue.

The "DUAL" mode does very little when working correctly, only a few degree variation is possible.

Before you jump into making changes, what specifically isn't working? Is the passenger side blowing hot and the driver size cool? The passenger adjustment **** only changes the temperature by 4 or 5 degrees. Hard to tell if it's really working. It doesn't change the digital readouts.
