Blown fuse, defective blower motor resistor pack, blower motor, or blower motor switch. This happened to me and I found a connector at the fan motor had fried. I changed the connector and it worked great.
because it's a 1997 ford explorer
Answerthere is a relay under the hood of the car located near the battery, i recommend replacing all of them cause usually if one goes out the others will be shortly following. I was wondering if that fixed the problem for you. I own a 1997 Ford Escort. I have had the blower quit on me twice or maybe three times. In those instances, it was because someone had been sitting in the passenger seat and had kicked the wire which caused the old worn out plastic connector to pull out. I just reached down there and plugged it back in. Awesome heater in that car by the way!
I have a 2000 zx2 and it has a thermostat, if that is your question. Having said that, my heater quit working and it turned out to be the cable came loose under the dash on the left side of the radio. At first I thought it was the thermostat but was wrong. Duct taped the cable in place and the control and heater started working fine again.
try the water pump my Malibu always ran hot and anti freeze would gush out i took it to a mechanic thinking it was the thermostat and it was the water pump
Check the alternator. Put a new battery in it or check the alternater.
Check or replace turn signal flasher
if you can not find it on the passanger side of under truck behind bumper you will have to go to a ford dealer and order a cord for it they quit putting cords on all the trucks around that time but the heater is in the block on all of them. some dealers did not spec the truck with the winter packege.
Check your fuse
check the relays.If it doesnt blow air at all then check the blower relay or fuse
you dont have the speedodmeter cable set in the transmission right take it back out and as u set it in place turn it till it seats flush on the transmission
it should be close to the fan in the front of the evap case. passanger side firewall engine compartment
because it broke.
