Heater problems !!

[oskar_subaru]

ok so i bought a 1987 GL sedan and the heater is not working on any speed, i think the switch works because it turns the light on the vent selector on and of between 0 and 1

 

the motor turns if i give it power, is there any resistor packs outside the switch it self ?

Yup, a common problem... search for it, it comes up quite often

that´s the thing, maybe it´s my english knowledge but i don´t find anything when i try to search for this

For info on the resistor pack:

EA82 Blower Resistor Pack Info

The blower should have 12v+ from fuse 1, 2, 12 and the switch should control the grounding to the motor (through the resistors to control speed)

 

Hope this helps

I had same problem, ended up just being blower motor resistor located right by the blower motor. I always thought it was a progressive failure, losing high, then next highest etc...etc... mine just flat quit working.

If it doesn't work on ANY speed it's probably the motor. Turn the car on, put the selector to max (I think it is "4" or something) and check for 12vdc at the blower (it's to the left pax side).

or possiably the relay itself

you get the dancing banana

 

tried switching one of the headlight relays for the heater one and surely enough the motor started blowing like a champ (was hoping it wasn't the motor, the car is only driven 102.000 km (60.000 miles))

 

thanks all though for great response, this forum never seizes to amaze

 

 

 

 

sorry about my spelling
