Electric Fan NO GO!!!!!
Hey guys heres the deal my nephew has one of these rides being a 1994 Ford Thunderbird 3.8 and he needs some help. The electric cooling fan does not come on when hot he has replaced the engine coolant sensor the temperature switch and no go! When you unplug the engine coolant sensor the fan will run. My question is could it be in the ECC or CCRM or does anyone know? Also is there some way to check the ecc or ccrm to be sure?? I am just unable to tell...............

Re: Electric Fan NO GO!!!!!
Hello bootleg233, Does the fan turn on when you turn on the air conditioner? You may have the low speed circuit working but not the high speed. There are three connections to the fan. One is the ground and the other two are the high and low speed feeds from the CCRM. The black wire will be the ground connection. When you unplug the coolant sensor and the fan turns on, use a test light or voltmeter to determine which wire is the feed providing power to the fan. When the engine heats up you should be seeing about 12V on the other feed wire. If you don't then the CCRM is highly suspected. BE CAREFUL OF MOVING PARTS!

Re: Electric Fan NO GO!!!!!
Hey Bird thanks for the reply.... his air conditioning has a hole in the line so it doesnt kick on so cant check it that way. I was suspecting the ccrm just wasnt sure if it could be the ecm also didnt know if it would run at all if it was the ecm but I will try checking. Thanks again for the reply.
