And as you guessed still no a/c or heat. My jeep originally only worked on high setting anyways but no it doesnt work period.

It worked great when I drove it to work. I pulled the jeep up on alittle dirt mound(doing the jeep thing I guess) and parked it. When I came back to it for lunch no air.

I looked for loose connections(not really sure to look at other than resistor) and didnt really find anything. I replaced the blower motor, no change. Then replaced the resistor still nothing, I did check all the fuses under the hood and in the thing and didnt find any popped.

I dont really know where to start from here. Ive heard something about the high low switch possibly needing to be cleaned but I have no idea if thats a good idea to start or how to easily get to it.

thanks

Given where you live, I'd suspect salt corrosion, but where? You need a meter and a schematic to check voltages and grounds.

Do a search on "blower motor" in titles, I'm sure you'll find a schematic, many have been posted.

Does one need A/C in Fla? I never use it where I live.

I'd pull the HVAC control panel off and look for a burnt connection/connector on back side. I'd guess you will find something

SILENT_SOUL

any tips on pulling the hvac? and i suppose I could get away with no air, however the driver window motor is shot. It was and so far still is cheaper to fix the ac over the window but its getting to the end of that cheaper rope.

Philips screw driver check fan speed switch very common issue.

SILENT_SOUL

ok thanks, i assume I check for corrosion and loose wires? or is it a replace not fix kinda thing?

bsmith97xj

Have to see what ya find....

SILENT_SOUL

i suppose I wasnt sure if I should wait to pull the dash apart though incase its a not able to fix and always have to replace kinda thing.

Burnt connector at fan speed switch usually .

SILENT_SOUL

well, i opened it up and found myself a burnt *** connector, melted and corroded.

I took some pictures, I did clean the wire and rewire in some new connectors and hooked it back up.....still nothing.

here are the pictures:

opened it up and found this ****


this thing was not connected correctly, so I fixed the retaining clip as I am sure it isnt supposed to be loose

under the tape:



cleaned it up and rewired:


still nothing, so I opened the box:


I cleaned that **** off, and wire brushed it clean like everything else.

Put it all back together and still nothing. anyone gone this far and still not get to the light at the end of the tunnel?

Melted plug at ignition switch? Do all other accessories work -- wipers, radio, etc.?

SILENT_SOUL

I havent looked at the ignition switch, everything else works, radio wipers windows(minus the driver one but that thing never worked) lights even rear wiper


what do I look at around the ignition switch more melted or corroded stuff?

Pelican

If the other accessory items work, it's probably not the ignition switch. You would look at the connector that plugs onto the switch at the base of the steering column. I believe the accessory wire is brown but not absolutely sure.

You checked 25 amp fuse #5 in the driver's footwell panel?

Aso, I can't tell for sure from the pics, did you check the rotary blower speed switch?

SILENT_SOUL

i looked at all fuses and couldnt find any blown. I dont know what the rotary blower speed switch is.

Pelican

Sorry, not the best description there. I was referring to the blower speed selection switch. You may have already checked that.

At this point I would start at the ignition switch with my meter and work outward till I found where the voltage stops.
