I have a positive wire at the controls but the AC button doesn't light up or engage the clutch. I would add Freon but with no blower that is kind of pointless.
Replace switch

looks like fuse # 8 "heater control relay- ac clutch relay-cooling fan" fuse runs the 12 volt side " black and yellow stripe wire " pcm or ecm runs the ground side "red -blue stripe wire"- what else do you need?

the blower motor resistor located in the heater A/C panel usualy under the glove box

Bruce did you check the freon. if the pressure is not enough the ac clutch will not engage. If it is the freon you may want to use a leak detector from your local autoparts store before wasting freon.

There was a bulletin reguarding water contaminating the blower motor, which overheats the blower resistor and renders it inoperative. The fix was to replace the blower and the resistor and seal the culprit hood cowl screw at the base of the windshield, which is the second screw from the passenger side. They say water drips off of it down into the fresh air opening.
Here's what I'd do: Assuming your switch and blower motor is good, replace the blower resistor. Remove the blower motor and see if it spins without any excessive drag. If it's okay, reuse it. If it's dragging, it will overheat your new resistor in a short period of time and you'll be back at square one. The blower resistor is mounted to the front of the case with 2 screws to the left of the blower motor. Remove the glove box and you'll see it.
The Hood cowl screw is straight down into the cowl, the second one from the right side, about 10-12 inches from the right fender. Pull it out, put some sealer on it, and reinstall it.

check the freon there are high and low pressure swithes and will prevent a/c from workin
