WTB: Need a 1994 Mark VIII Variable Control Relay module

[HOTLNC]

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?

check with racebronco2 before paying the ebay price.
he will sell cheaper through the forums to avoid ebay fees usually,.

Thanks for the replies. I'll check with him.

For 94/95, you want F4LF-12B577-AA. I believe the 93 units, F3LF-12B577-AG and AH can be used.

 

[chris2523]

yes 93-95 should all interchange.
i have the f4 part numbered unit in my 93.

racebronco2 came through for me. A new "used" VCRM and the car is up and running. The A/C and fan is working as it should.

Now I gotta pass inspection <sigh>

Excellent news. Good luck with the inspection!

It passed!!!! NOx levels below standards by 3 (low speed) and 4 (high speed) points. Skin of teeth type pass, but still passed.

I guess there ain't any excuse not to roll the odometer past the 300K point.

Congratulations! Now: go "ride," and burn out the rest of that carbon

XO2 should read Nox. Oh well. It passed.

Yep, gotta blow out that carbon.
