Poor Heat

[Nocturnall]

Engine heats up like normal but no hot air comes out of the vents in my 97 explorer. Any ideas?

Drive a couple of miles with the heat turned to max. After shes good and warmed up, feel BOTH heater hoses where they go into the firewall. If both are good and hot, you have coolant making it thru the heater core, and you should have heat.

If they are both good and hot, your fan speeds change like they should, and your a/c comes on when you turn the control knob to the appropriate positions, your controls are probably working ok and you need to research blend door fix / repair for explorers on the net. The blend door actuator breaks, and the door quits moving. About a $1,000.00 for the dealer to pull the dash and fix it, or a few bucks if you are willing to do a little shadetree mechanic work.

Hey, you're still around! I'm still trying to exercise the gray matter a little.


Working on the p.c. - got a trojan. Got a question for you - I'll p.m. you as soon as I get the computer tied down.
