Changed Fuel Pump...now AC controls don't work!

Radio is fine, all gauges and such seem to be normal.

The climate control unit displays 75 degrees, the fan is blowing, but none of the controls do a darn thing. I can't turn it off, up, down, or anything. Any ideas where to start looking?

I assume you have the dual climate zone control since you have the digital thermostat.

That control unit has diagnostics described here (http://www.automotiveforums.com/vbulletin/showthread.php?t=972162). You may not be able to get to them in its current state, but you may want them later if problems continue.

First thing I would try would be to pull the fuse for five minutes to see if that resets it.

That's all I got right now. Good luck.
