just re-installed the heater core, and now the blower is not turning on w/the lever (4 position switch on dash).


what could be wrong.
its a "new" blower, and was working fine before.
is there more than 2 plugs that get that thing going

i want to test the new heat.

 

i had similar problem, something in that speed selector went in the middle of the winter in my 88pickup, it was minus f$$k off degrees out and i wasnt in the mood for troubleshooting so i took the wires that went to the blower motor off spliced in cigarette light plug to the end and just plugged it into the lighter. Just have to figure out which wires make the blower turn the right way and not suck air instead. The blower motor will be on full mode only, but its better than nothing, afterwards i wired it into a switch and never bothered fixing any further, as when its winter i always had it on full anyways

 

there should be a plug going to somewhere around your heater box. on the inside of the box its like a resistor looking thing. check it....i know on some other makes they have this, and it has everything to do with your fan.

 

One thing you may want to check too is the blower relay. It have have gone out on you somehow. That relay should be behind your glove box and cost 17-25 dollars depending upon where you buy it.

Hope that helps

 

thanks everyone.

i saw that relay, and its a bear to get, so i left it dangle, just in case.
and
if all else fails, i can hopefully just put it on a toggle.

 

A bear to get at??? 5 screws and the glove box comes off and it is right there. I have mine just go as well. Damn winter...............

 

well, the heater core was a bear.
