i need to replace the fluse for the heater switch and i can not figure out what fuse it is. i purchased this vehicle used so i have no owners manual and you get view one for a 1997 on line. I need to have a layout of the fuse panel for this van. Can anyone assist me as to what number it may be or if and where i can get a layout. I have changed the heater switch but it still doesn't work so i want to change the fuse or put one in a missing slot to correct this problem.
Hi clncrpt(No Email Addresses In Posts!). Welcome to FTE
The shop manual shows fuse 13 under the dash as being a 15A fuse for the heater functions selector switch and the blend door actuator. It also energizes a blower motor relay in the underhood fuse box. There is also a 50A fuse 13 in the underhood fuse box for the blower motor. It doesn't show which relay is for the heater motor but you should be able to feel it click when turned on. The blower motor relay sends 12V on an orange with red stripe wire to the blower motor. The blower switch controls the ground side of the motor through the orange with black wire.
I would take a test light or voltmeter and check for power at the blower motor after I checked all the fuses. If you have power at the O/R wire at the motor try grounding the O/Bk and see if the motor runs. If it does you have a problem on the ground side from the switch to the resistor to the motor.
