alright well ever since my swap my heater doesnt work. i have the heater core hooked up but when i moved the levers nothing happens. i was looking under the hood and it looks like i dont have some things plugged in but dont know where they go. any way i can rig it up to at least get some heat?


heres a pic of the plugs and stuff

Ok, lets work throught this.

First off, does the blower motor work? I dont think it is, because you've left the blower motor resistor unplugged. Plug it up. Go to next step, if no heat.

Second, after the engine is at operating temperature, are lines leading to the heater core warm? Both lines should be roughly the same temp, if not you have a blockage or air pocket.
-Neither line hot- not recieving coolant from engine.
-One hot, one cold- remove lines from engine and reverse flush to check/clear of blockage.

Third, post your findings.

the blower motor resistor plug is the one that has the 2 purple wires coming out of it? if so i tried plugging that in and got nothign. the heater hoses are hot goin in and out. no air pockets cause i used a vacuum bleeder instead of burping it.

Yes, that has to be plugged up for the blower to operate. Plug it up, get a test light or voltmeter (your preference).

1. Connect test light to ground.
2. Check purple wire pin at blower motor for power.
3. If have power on purple wire, connect test light to 12vlts (battery positive, alternator wire, fuse panel, etc.) and check black wire pin for ground.
4. If both power and ground, bad motor. If no power, go to next connector on purple wire and test for power at resistor. If no ground, check ground.

what plugs into the little 4 plug connector in the center of the pic?

i was tryin to go off this but couldnt tell

HeavyThundar

I was looking at my own schematics trying to find out. The wire colors in that connector are Green, Light blue, black, and red right?

yeah looks like it. i think the red needs to have constant power.

HeavyThundar

More than likely it should, considering its red, and the wire size. Im kinda lost on that connector. Makes me want to go check out mine and see, but its in the shop down the road and im at the house for the night, ill be out there first thing in the morning tho.

The relay mounted right beside that connector (with the purple, orange, black, and red wires going to it), that should be your blower motor relay. Does the red wire coming out of it, go to that 4 pin rectangular connector? (it looks as if it does in the picture)

yeah it does.

HeavyThundar

Ok then that has to go to as wiring diagram says, fusible link. But im not sure where the fusible links are located.

probably in the stock tpi harness which is gone. wonder if i can wire one up myself?

HeavyThundar

Yup, Cut that red wire out, and connect it to battery voltage, with a 25 amp fuse inline. Only would take about 3 ft. max of red insulation wire, a couple of heat shrink butt connectors and a eyelet connector to bolt down to battery power.
