Uplander Rear AC fan not working

The rear blower motor is located behind left rear interior body panel

Both front and back blower motor quit working suddenly. I checked the fuses (under the hood and on the passenger side all good) for the blower and they are not getting any electric to the fuses, the primary fuses are all good. I have tried switching the relays with known good ones but still did not work.

If the fuses are not getting power pull them out and try using dielectric compound on them see if they work then. It may be corrosion in fuse box. Check items in pictures and if still no power then have it scanned for codes by a mechanic as it may be a body module problem.

The heater fan wire in the motor section is disconnected. Gray wire with black corigate tube on it that goes through the fire wall to the front.I am trying to find out where it connect. Is this the grownd wire? Can I connect it anyware? Since this wire have been disconnected the fan control, 1 to 5 does not work can you help me tx.

Before you ground it, make sure it isn't a power supply. If it is a power supply, it will blow a fuse. I will try to find a schematic.

Thanks for the advice, now the heater fan is working? Maybe coincidence. Still didnt find out what this wire is connected to or what is its purpose?
I will check in an other uplander to see exactly where it connec.T thanks again for your help.

Hope I helped

Yes, I probably would have blown some fuses or get the car on fire. Tx Nelson
