Heater vent fan doesn't work. Help me!

[baartman]

My heater in my ae86 still doesn't work even after I replaced the heater motor. When I open the switch, the relay clicks. That's it. Does any one know my problem?
Thanks.

Try a new relay or swap it with another one, If thats the heater that I sold you and yours still works I will take back the one I sold you if thats the one your friend picked up ( it worked in my car)

OK, I'll see if the old heater works. Where is the best place to get a relay?

Also, I checked the fuse, but I'm not sure if it's the right one. I checked the one behind the pass. side kick panel. It was slightly corroded and green, but the fuse was okay.
Thanks

if its blowing cold air
check ur thermostat
and check for a blockage

The motor does not engage. No air is blown.

I went through the trouble of ripping apart my dash looking for this and that to be wrong. In the end, it was the 3 little resistors located up inside the blower unit. Three bolts takes the blower unit off (behind the glovebox) and then a few screws.

I don't know if you can buy these new or not ...

Good luck!

I know what you're talking about, the three resistors... well.. they're gone. the carbon at least. So, I'm not sure why this would cause the motor not to turn. I'm sure that I can find some somewhere.

Anyways, I tested the motor directly and it works.

Then I put the motot back in and...nothing.

So to be sure, I need to know exactly where the fuses for the heating unit is. Maybe I checked the wrong ones!
Thanks again
