96 ZJ - No Blower Motor

Hello Everyone,

Was trying to see if I could get some hindsight on how the system works.

Currently I have no blower motor, tested for positive had it and replaced motor, still a no go.

Went in for some further diag and I don't have a ground to the motor? It also appears I have a constant +12v on the positive line. So is this a switched ground system? Where would you look to start on fixing it. Checked all fuses/relays.

Have the manual controls

Check the connectors on the front of the heater box for pin damage from overheating.
There are usually visual "burny marks and meltyness" (author: ratmonkey)

Looks something like this





Some cut the connectors out and splice all the wires together.
Or just bypass the connector with damaged wires spliced together.
