smoke from dashboard, wire burning smell, no ac fan
Question:
I have yet to figure out how the leaves got in there to begin with. The holes over the air intake are too small leaving only the gap around the base of the windshield wiper arms as a point of entry. Granted, the car is now 8 years old and I’ve got oak trees all around me, but it sure is puzzling how I could have gotten enough of them in there to jam the motor and blower assembly….oh well. dave – Hide quoted text — Show quoted text -> Sorry to here that.

You’re making me wonder if I got completely hosed by my Ford dealer. This same exact thing happened to me as well. My fan failed to come on, the resistor heated up and started a bunch of leaves on fire. The dealer said I needed the fan and resistor replaced….I should have made them prove to me that the fan was defective. dave – Hide quoted text — Show quoted text – > Newsgroups: rec.autos.makers.ford.explorer > Thanks to all who responded to my post.

Sorry to here that. I posted my fix at the alt.ford newsgroups and someone replied why did the whole leaves get in there. We need to check to see if there is a screen missing or broken over the air intake grill. Don’t forget to peel back the foil heat shield over the evap shroud and check for holes. Maybe you can go back to ford and hose them for a free check of that. Just out of spite. sperez – Hide quoted text — Show quoted text – >You’re making me wonder if I got completely hosed by my Ford dealer. This >same exact thing happened to me as well.

Sperez: Classic symptom of blower resister failure. Very easy to remove/replace. Under the hood back by the A/C evap. and blower motor. Look closely under the hoses that attach to the heater core for a small rectangular piece with some wires attached that is mounted into the ductwork. That is it. Remove and replace with a new one from your favorite ford store. HTH, -Steve (‘94 EB 4×4)

Got the part today will install over weekend.

Thanks to all who responded to my post. I got the resistor pack from ford for about 24 dollars. While you are there you might want to pick up a heater bypass valve. I broke mine trying to get too the resistor pack. The valve is made out of plastic and it was brittle. I removed the resistor pack and I found leaves attached to it. Burnt leaves. But wait there was more I pealed back the protective foil on the evaporator housing and WOW two huge holes in the plastic. The burning smell was leaves catching on fire and melting the plastic housing. I patched the hole with some aluminum tape and replaced the resistor pack and the heater valve ($18.00). Checked for leaks and now I have ac fan speed controls again. !!

Response:
Ok so I’m driving down the road with the AC on and all of a sudden I smell burning wires. Smoke comes pouring out of the dashboard vents and now I only have High fan setting on the AC. Any suggestions? 1994 explorer xlt with standard ac controls. (no auto temp). TIA sperez.

Resistor pack for the blower motor. When you select lower speeds the electricity is routed through resistors. This lowers the voltage at the motor and makes it go slower. Look for it to be mounted into the ductwork. Probly see it from the passenger seat. Maybe behind glove box.

I have to ask. It is January. Where the hell are you that you need A/C?

On many newer cars, the AC comes on with the defroster. Or, here in Phoenix lately, it’s been warm enough to maybe want the AC if the car’s been sitting in the sun. 78
