A/C and fan speeds

[Meir]

hello thom.
the fans are controlled by 4 different relays, located above the fuse box on the driver side kick panel.
you can remove the relays and "jumper" legs 30&87, to activate each fan in its relevant speed.

let me know if you need more details, i will try to post some pics.

you should be able to activate each fan separately, both in high or low speed.
if one of the functions doesn't work, it usually has to do with defected fan resistor.
with that said, when the fans are on low speed, it is very hard to hear them.

Thanks Meir:

I tested the relays by putting my finger on each relay and pushing the snowflake button to activate the A/C. When I do this, the relays click, which I could hear and feel. I still can not hear either fan on low speed.

So my next move is to jump the pins. Here's my follow up question. When I pull the each relay, how do I know which pin is 30 and which is 87?

Most relay have them labeled on the bottom by the pins.

Following Tony's excellent pic,And just to clear.
leg 30 is the center vertical, and 87 is top horizontal.

Thanks everyone for the advice. It was very helpful. Unfortunately, it looks like bad new for me. When I jump the fans to test low speed, neither one comes on. When I jump the fans to test high speed, both work. It looks like I'll need two ballast resistors. I'll have the independent shop test in the morning using its computer just to make sure. Again, thanks
