heater problems f150
 

I have a 1996 f150 2wd regular cab with 5.0 engine. The heater isnt blowing hot air. I replaced the heater core and that didnt change anything. any suggestions? the blower works and a/c works just cant get heat

theme of the night I guess...

check the cable going from the temp control to the temp mix door. it has a tendency to come off, might be a simple fix.

also, a lot of people seem to have problems with aftermarket replacement heater cores not working well... so if the heater blows slightly warmer air than the cool vent, that could be the problem.
