Its a 1995 cobra, so its an elec. fan. I took a test light to the connector going to the fan and i seen no power.

the ccrm controls fan operation by an internal relay the ccrm may be bad = black box close to the overflow bottle

yeah i know where it is.... also the AC clutch is BARELY operating, and i was having a slight problem getting it to fire up (fuel pump?).... doesnt the CCRM control that, too?


well, in any case im going to swap the CCRM from my 94 GT which i KNOW works into my 95 cobra. Would that be compatible??

i know how the mechanical and electrical fans works, thats why i said run a hot wire cause a mechanical fans going to start spining when you first start the car, and he said he turned the a/c on to see if the fan comes on, and elctrical fan is suppose to always come on when the a/c is turned on, cold or hot

I believe it does control all that

for the record

the Fox temp guage... is a vertical Scale... spelling Normal from the L up...

sn-95 temp guages are horizontal... spelling normal from starting from N on the left side

If your AC clutch isn't workign correctly then the test with turning on the AC to verify the high speed fan is coming on wont' work.

The function that activates the relay on the CCRM when the AC is turned on is a pressure switch in the AC system. so no pressure = no fan when Max AC is turned on.

Here is the wiring diagram I used when trying to figure out if my system was not working correctly.

Sombody please correct me if I'm wrong because i'm not 100% sure.

AND THIS HELPS RESOLVE HIS PROBLEM HOW???

Sombody earlier said that if the temp was by the L then it was way low. Whoever said that probably based it off of the Fox Scale vs the SN 95 where L in NORMAL is on the high side.
