Power windows don’t work Caravan

My power windows don’t work Caravan

If the power windows don’t work along with the radio or blower motor or the problem is intermittent, this may be your fix.

Caravan owners may experience a situation where the radio, power windows, blower motor stop working all at the same time. The problem may be continuous or intermittent.

Shops are reporting that battery acid is corroding the wiring harness. The Front Control Module (FCM) then senses stray voltage (1-5 volts) and shuts down the accessory relay.

Check for corrosion or a short between these wires:

1) Yellow wire between the ignition switch and the Intelligent Power Module (IPM),

2) Yellow wire between the IPM and the transmission control module (TCM),

3) Dark Green/Orage wire between the PCM and the IPM.

You can try to clean the wiring harness, but most likely you will have to replace it.
