    That won't solve your problem so don't waste your money. I'm almost certain that your low speed fan relay isn't kicking in. Just try connecting a length of wire from pin 14 of the CCRM to a 12v source and see if that makes the fan come on.

    Still sounds like the same symptoms as I had, did you wiggle the wire going into the fan motor? After opening mine up I found that the brushes were worn causing not to work on low speed.......

    I agree with you I really believe it has something to do with that CCRM.
    I dont know how to do the test. What do you mean by 12 volt source?
    I'm thinking about going ahead and getting a new CCRM.

    Wouldn't a KOEO test let him know if the low-speed fan was turning on?

    A new CCRM is in the $110 range - if you have that kind of cash to toss around, go for it.

    What did you open up? The fan or the CCRM?

    Yes,a KOEO test will check both low and high speed.

    Before you spend your hard-earned cash on any parts, here's what you need to do (ignition off).

    1. Get a 3' length of automotive wire and connect a small crocodile clip on each end.
    2. Locate the wire going to pin 14 of the CCRM and make a small break in the insulation to expose the wire underneath.
    3. Connect one crocodile clip from your test wire to it.
    4. Touch the other crocodile clip of your test wire on the positive battery terminal (12v).

    If the low speed fan doesn't come on, it's likely that the relay inside the CCRM is blown. To confirm that, try hotwiring the fan. If the fan does come on when you do that, you'll know that the CCRM is the problem. If it doesn't, the problem will be inside the fan motor.

    Thank you Bullitt.

    You set it out very clear for me.
    I'll give it a shot. I reallly think the issue is with the CCRM or the fan.
    This car is in great running shape and never gave a hint to this happening.
    Hopefuly its an easy fix.
