moved wires by heater under hood...no heat now!!!

[1985GN]

hey guys i was trying to tide up some wiring under the hood and over by the blowe motor for the heater. i took them off and re routed them and all. i plugged them all back in and now i have no heat. the one thing that i think iw wrong is there is a vaccum hose going ot the blower motor that popped off and i thoght something went flying. i wedged the hose back into it and trued again and no heat. is there a fuse under the dash for the heater i may have blown that. it was working fine last night i just had to mess around wit the wires and now im screwed. let me know waht to look for or send me a pic of the blower motor so i can look at the wiring and all, thanks alot guys its getting cold here soon.

If you have an '86 wiring harness look for the fan power connector near the power antenna wiring in the back fender area.

Should be a square type connector with a fat red wire in it that corrodes at that point.

It will kill the fan.

Clean up the wiring or cut it on each side of the connector and solder splice it together.

Sometimes it's tucked down into the fenderwell area behind all the relays and left of the fan motor.

if i have power in the red wire going into the connector haning off the AC box but not the purple wire coming from it woultn that mean the red wire is fine??

Try tapping on the blower motor relay. Silver metal relay and bracket near the blower motor.

Key on, fan on of course.

On High position fan gets power from the red wire through a second set of contacts in that relay.

I'd check the resistors themselves and follow the purple wire inside the housing.
