Heater

I'm too lazy to type it out now, so here: http://gbodyforum.com/viewtopic.php?t=5082

Here you go. Shanezoid.

Did you ever figure out what was the issue with the high setting?

hold on a sec

The resistor is in blue, the relay, I think it is, is in the red.

Hope this helps.

I remember having the same issue with my first gbody about 20 years ago and it turned out to be the blower switch on the climate console...

I guess since the gbody is now aged that it could be some other issue due to the aging of the car...

How do you check either one and were you guys able to see my pic I reall still have not figured posting a pic out. Shanezoid.

Can some1 post the schematic of this crkt so we can tell for sure which relay needs to be checked? I'm sure you coul just check both relays out of crkt with an ohm meter?

 

[foxtrot]

I still think that the relay behind the AC dryer does control the high speed of the fan because high speed for AC and heat are at a different RPM….

Going back to page one in the picture I put up, I think it is the blue one that controls the fan speed. When I did a heater core in my 87 Nissan truck I took out the A/C and left the resistor out, which is the same as I circled in blue. The heater fan speeds did not work,the fan didn't work at all for that matter.


I think they are all $20 parts so I guess go with that and if not bring it back. I tried to check the OHMS and without a schematic I can't do it, mine has no high speed either.
