AC Blows - no other controls

278 Views 4 Replies 4 Participants Last post by  Chuzz
AC Blower works.
Have no control over the heat/cold
No control over air direction (max, upper vents, floor vents etc.)
AC button doesn’t work
rear defrost doesn’t work
Recirc button doesn’t work.

is there a way to trigger it to stay on Max AC all time? Can I jump two of the wires to trick it to stay on?
It’s Florida. We don’t need heat.

Welcome to forteforums.

Did this just happen? Was any work performed prior?

Sounds like an electrical connector is loose OR a fuse is blown.

Time to look at your fuse boxes - use your owners manual and look up the fuse box locations.

Check to see if the wire harnesses, plugs aren't shorting out or not connected correctly.

The AC/HVAC assembly control until is know to over heat causing connection problems softening the plastic plug, socket wires/pins become loose, burn or short out.

Check the circled areas of the HVAC control aren't burned, loose, warped plastics. Solder connections can come off/loose causing no operations.

May need to disassemble & see if the soldered knobs connections aren't loose or need to be resoldered

Thanks for the guidance. I bought a replacement HVAC control on ebay thinking that was it. No dice.

For a while, it would come on and work for a little while, then shut off. Lately nothing at all.

I checked the fuses, and the fuses are fine. (left side by driver's door).

I just checked the power at the fuses, and found no power on the top three fuses on the left side. Now looking for a wiring diagram to see if there is a relay or something before the fuse that i need to locate.
Sounds like you're going to have to trace some wires. Good luck with that.
