'97 explorer heater

[andri]

Hi all

I have a problem with the heater/ a/c in my xlt. The thing is that a couple months back when I bought it the heater wasn't heating that much at all. When the a/c or max a/c was switched on It cooled normally. But now two weeks ago or so it started acting up. Now it only heats, and heats alot when in heater mode, so I can't just select cold on the heater. It also heats when in a/c, but cools just as before in max a/c.
I suspect either the blend door or the actuator, but I'm still a bit confused since the heater changed so suddenly.

i would check the motor, might be dead. check your switch that might be dead. if your getting power the the switch but none at the actuator plug its a god chance its the switch that is dead. check you fuses too
