Hi All and thank you for having me.
I have a 2000 wrangler and the blower motor stopped working.
so far this is what I have done.
1:confirmed fuses are good both under hood and behind glovebox
2: replaced switch
3: replaced Resistor
Plugged wires into back of fan and nothing. Nothing at any speed.
I have removed fan from car and direct wired to battery and fan works fine.
I put a multi meter across the connector that plugs into the back of the blower fan and with ignition on was getting a good 12 volts at the high switch position (4) when I reduced the switch position 3-2-1 it altered my reading at each increment but I did not take notes of the exact figures while doing so. ( balancing act )
I assumed that maybe the connector was bad so I cut the connector and wired two spade connectors to the ends and rechecked voltage and again 12 volts . I plugged them into the back of the fan and again the fan did not run.
Next , Ignition off. I put the continuity meter across the two wires to determine which was ground . I then conected only the positive wire to the back of the fan and I grounded the availible fan contact.
Ignition back on and switch in position 1-2-3 & 4 the fan ran at what would appear to be full speed
and would stop when the fan switch was in the off position.
Sorry for the length of this post but I wanted to give you as much info as I could. Any tips would be fatastic
Thank you in advance
