I'm in the middle of 2 project.. the EFI and replacing my heater box... I SHOULD have just done the vintage air.. but that's another story.... the blower motor is new and works with direct power to it.. there is power to the fuse box heater fuse..but not to the motor... there is a connector on top of the heater box that plugs in.. that also doesn't have power.. I cant seem to find a wiring diagram.. help?? there must be a relay somewhere...
It's a miserable pdf file, but it's the ONLY thing I have ever found.
Illustration 12-11, but I know that book pretty well.
The gizmoe on the heater box is a resistor or relay. If it craps out, it's a no fan production. All wires are + so it's impossible to hurt/short anything by playing around with a jumper wire in the wire connector.
Thanks! I have tested that plug that plugs into the heater box. No power on all 3 wires. I can’t find the relay. I’m gonna have to tear the dash apart again to find where the wires go.
I pulled the plug on the heater control itself and theres power that far... has to be that switch... this turned into quite a project.. lol.. I thought the efi was gonna be the pita...
