I'm looking for a 1994 Mark VIII Variable Control Relay module (F3LF-12B577-AG).
I think mine has bitten the big one.
I removed the old one. All connectors look clean. I cleaned them anyway. Inside the module the PCB looks pristine. Nothing burnt; no visible damage.
The only thing left to do is see if it is getting power from the fuse box. All fuses good.
If I can't get a VCRM, I may have to install a switch to drive the radiator motor so that I can turn it on while the car is not moving or trying to run hot. I'll also try to enable the A/C compressor clutch through the pressure switch. I may need to use a relay.
I wonder if I can kludge in a truck fan controller module? Hss anybody done that?
