heater stays on hot

With the controller on cold it still blows hot. With the AC on it does blow cold. My wife doesn't like AC but can't stand it blowing HOT air. Is this more likely a controller or whatever drives the hot water valve?
Oh yeah, it's a 2001 Bonneville. Thanks, Mike

Welcome…

Auto climate or manual?

I guess you'ld call it auto. The temp control knob feels like a rheostat.

I pulled the controller out and opened it up. Nothing looked burnt or had gotten hot. Put it back in and now it works, maybe a bad connection. I'll leave the trim and glove box off for now and see if it keeps working.
