WBN3 How did you resolve this problem? I found my plug melted today and need to source a replacement (in addition to replacing the blower motor).

RUBI 4 MY MRS I should add that the reason the melting happens (not that uncommon) is thought to be the blower motor, with age & use, wears enough & starts to drag causing the amp load to increase & overheat the wires. A new motor might be a good idea.

RUBI 4 MY MRS If you go to the Morris 4x4 link above & pick '96-'97 & go to the wiring diagrams & to chapter 42 the page that shows the resistor has the resistance of each resistor. They are not shown in any later yrs for some reason.

Failed HVAC fan part 3 - The saga continues...

OK, I found the fan resistor pack and when I removed it, it was filled with furry debris (think clothes dryer filter). Removed the first clump and the fan came on. I blew out the rest of the junk and reinstalled the pack. OK great right ? An hour later, the fan was dead again. I took the pack out again and noticed that one end of the connector was melted. The connector still unplugs.

I want to use my ohm meter to check the pack. Does anyone know what the readings between the pins should be ? Also, the connector is garbage and I'm thinking of soldering the wires directly on the pack pins or using crimp push on terminals to connect the pack. Seems like a bad situation for a connector and wire insulation to melt.

Thanks in advance for any help. Jim (98 TJ Sport)

I'm trying to troubleshoot this dead fan before I pay massive $$$$ for a repair.
I can't locate the fan or the speed control resistor pack. It looks like I may have to remove the entire dash ? If anyone has been through this I would be grateful for any assistance.

Thank you all and have a great week !

Jim
