99 ford explorer air conditioner not working

Asked by Hayley Jul 10, 2020 at 01:27 PM about the 1999 Ford Explorer 4 Dr Limited 4WD SUV

Question type: Maintenance & Repair

My air conditioning and heat won't work. We thought it was
the blower motor because it was working then it just
stopped one day and wouldn't push any air out. We
replaced the blower motor but it still wouldn't work, we then
replaced the resistor and still nothing. We have no replaced
the climate control unit in the dash that before would at
least turn on but now does nothing, the new and old one.
We are stuck what could be the problem. The compressor
works fine and we had charged the ac at the beginning of
the summer. My husband and I are unsure about what to do
now. I'm 6 months pregnant and have 2 other children and
can not afford to have a vehicle that doesn't have working
heat in the winter or ac in the summer.

It sounds like you have isolated the problem to something other than the blower itself. If that is the case and it also is not the resistor module (this controls the speed of the blower), then it must lie in the circuit hat sends the signal to the motor to turn it on. It may be a bad component that sends the signal or you need to replace the whole module (expensive but maybe needed). Professional assistance may be needed.
