A/C--FAN CONTROL SWITCH QUESTION

[MIDNIGHT RIDER]

In an attempt to track down why my blower switch makes my electronic tachometer go wild, I undertook to have a look at the fan-speed switch.

I removed two screws above the radio and a whole plastic panel eased out in my hands, to be layed aside.

Oh goodie, I can see the whole switch mechanism, held in place by four little screws, no problem.

I remove the four screws.

I jack and twist and wiggle and no way is that switch panel going to come out that hole, where it would make sense for it to come out.

Some moron at Ford Motor Company, in all their wisdom, designed the switch-panel to screw in from the back, behind the plastic dash holder thingie.

Try as I might, I could not get that switch to work out that nice hole that common sense says it should.

I looked at the radio.

Maybe if I remove the radio, I can get the controls out that much bigger hole.

I take out the radio, and guess what---there is a big steel panel between the radio and the A/C controls, no way to get it up there.

Many many years ago, I had to replace the vacuum controlled part of that switch, but I can't remember exactly what I did.

Please tell me how on earth that the A/C control panel can be gotten out where I can examine, and possibly replace, the fan-speed switch.

All I managed to accomplish was to knock out my radio memory that takes about two hours to reprogram.

Thanks.

Well I Just did this exact repair on my 90 Bronco. Remove the 4 torx screws retaining the climate control behind the bezel around the climate control / radio.

From there you will need to wiggle, pull, tug, twist, what ever it takes to get the climate control out. Mine was tight but I managed. I found it easiest to pull it part way out, then un-clip and detach the wires from the HEATER Blower switch.

You will need a 1/4" socket to remove the plug from the climate control assembly from the underside.

It was a PITA to do all this but I managed to get it out and my problem was a burnt switch and burnt connection on the wire assembly end. I had to remove the wired from the big piece of plastic (burnt by switch) and rewired the whole thing. I replaced one wire that was damaged by heat and now my Air and heater work real good.
