My 1992 Saturn has heat until you change the blower speed what is the problem?
Probably the blower motor resistor is shot.
under the blower motor housing. to the right
specs on how to replace a heatercore on a 1993 ford explorer
The blower motor speed switch is burned out or the fuse is blown.
Maybe Hi-speed fan relay defective and not opening
The blower resistor is located behind the dashboard. It is found behind the heater near the center of the vehicle.
usually mounted on or next to blower motor
Looking at the picture in my Haynes repair manual it looks like the blower motor resistor is in the engine compartment mounted just to the right of your blower motor when looking from the front of the Explorer - Helpfull
If yourtalking about the heater blower, I believe they are hidden behind the glove box inner liner.
The blower motor is on the right side of the engine compartment on the firewall.
Most likely and bad blower motor resistor.
probably the heater core is plugged
in another post, it says it is behind the glove box...take it out, and it should be right there.
Thermostat possibly stuck open or heater control valve broken. Now if you mean the blower motor has stopped working, check the fuse, blower motor itself, or the blower motor resistor pack.
remove the glove box and there are three relays one is for the control door
check fuses,see if ones blown check power at blower, don't forget the fan switch ,there famous for going out.
i believe the heater motor is locted under the hood on the fire wall on the passengers side,no need to remove the dash
REMOVE GLOVE BOX, REMOVE ACCESS PANEL ON HEATER CASE, REMOVE HOSES, REMOVE HEATER CORE. REVERSE PROCEDURE TO INSTALL. AVG TIME 1/2 HOUR.
double check that it's the motor most times it's the resister for the fan speed In the firewall on the passenger side of the truck is the blower motor speed resister coils, they burn out alot. I could not find one for my Dakota so I got one from a dodge caravan and I changed the wirring, that is the most likely problem
Defective blower motor?
If it has a block heater it will be installed on the passenger side of the engine , in place of one of the freeze plugs ( core plug , expansion plug etc )
The problem is most likely a faulty blower control module.
Yes. First check to see that you have 12 volts to the blower motor. If yes, blower motor has probably failed. If no, it may be the blower motor relay or there is a speed control resister pack causing your problem.
I'm not a mechanic/technician but the 1995 Explorer transmission is a 4R55E (electronically controlled) transmission and the 1992 Explorer is an A4LD transmission so I don't think so .
