BHad to abandon

I was trying to get tp the resistor under the dash, couldn't pull that off, Buttoned everything back up and the Compressor started working. The Fan still isn't working, I had to order a puller to get the Whipper arms off to try to get to the resistor from that way. Any Thoughts? I could reunn the fan with a +/- Power probe so I have to assume the Blower is OK.

I think the blower resistor is at the top of the dash and you might be able to access it from the top when you remove the panel by the windshield.

After Checking and replacing Resistor pack, Blower motor, it started working out of the blue, then quit again. I saw a cluster of wires and a connector to the left of the glove box opening I moved the around and every thing started working. It's 113F here today I cant stay out very long to work on it, I'll get up before sunup in the morning and see what the fix needs to be

Yeah, no point cooking yourself. Go back in the A/C. Worry about it later.

Everything is working BUT When I try to secure the Dash snug every thing stops, give it slack and all works again, I'm going to just button it up with some slack in the dash and fight another day.

The problem all along was intermittent loss of ground to days. Seems to be fixed now.
