Today while driving I turned up the heat control a bit to take the chill off and noticed it would not warm up (after the engine was up to temp of course). Turned it for full heat and still nothing. I then turned the vent control to upper panel and got full heat but then when I turned the temp control down it continued to blow hot air even at the lowest setting. Its still blowing hot air after a 20 mile trip.

I checked fuse 5 and 25 and both were OK. Do you think its a cable issue pn the temp control or is the control box itself a possible cause? Any tips or suggestions would be greatly appreciated. Thanks.
