radiator fan

[Jcoopacr2000]

Help, radiator fan will not come on , car overheating. Changed 50 amp fuse in fuse box, still nothing. Checked all wiring, appears ok. Is there a sensor that tells the fan to turn on? Where? Any thing else i can check ?

Check your Dual Pressure Cut Off Switch located on the Filter Drier. My A/C lost some Refrigerant this winter and opened the DPCO switch, the A/C Clutch and Fan motor would not come on. Recharged A/C and all is well.
The DPCO switch is normally closed, use an Ohm meter to see if its open.

Also, the dealers have a tool to check _all_ of this... the DRB. so if you have a friend at a dealer w/ a DRB, it'll check it out in 5 min or less.

good luck!
