The first thing that you need to check is to make sure that the blower motor has power and ground and after that check the fuse and the control panel..............
you have a bad heater core
bypass valve not opening
it wont blow heat itll blow cold air
hi my ford f350 heater blower wont run.was trunning then stopped. Where is it located
Open hood . Disconnect blower module located near blower fan. Disconnect, if blower shuts off, repalce module
Check for loose wire connections also Defective blower motor or resistor pack. Blown fuse or defective blower motor switch.
The blower motor is shot, if it doesnt come out of the vents, feet, windshield, anywhere, its the blower motor, take it in and get it fixed before winter comes, your heated leather seats wont keep you warm enough bud.
there is a condenser on the heater housing it has 2 bolts holding it into the housing, just below the heater motor, they go bad, i had the same problem on a 95 rodeo.
did your heater switch go out all of a sudden or did some work like high work and low not work? if some worked your blower resister is most likely bad under your glove box
Check the 30 amp Blower fuse. If not that check the fan relay, if not that check the blower motor directly from a jump on the fan itself.
somtimes a mouse moves into the blower motor and makes a nest ?
Blower wont work on all 5 speeds, usually the lower speeds tend to go first.
