Default A/C wouldn't get cold, fixed it, now won't get hot

Help! I had the dealer replace a trashed condenser, and now my A/C runs ICE cold
even with the temp set for 90degrees. The weather here turned cold and very wet today
and my windows were fogging, so I had to run the fan at full blast, ice cold, to keep them
clear. I almost died of hypothermia!
Is there an inside air temp sensor, could that be the problem, and, if so, where is it located?
If I know how to get to it I can swipe one from U-Wrench-It

To the right of the cigarette lighter is a little vent. Inside is a interior temp sensor. It could just be covered with dust. Take the trim panel off and clean it. See if that fixes the problem.

Do you have any flashing temperature digits on the display? Does the outside temperature read accurately?

Sounds like the blend door is shot. Although if it was, I would think the climate control would detect this. Do you have a service manual?

I would agree on the airmix door. But I'd be taking it back to the shop ASAP and making them fix it.
