My daughters a/c didn't work when she turned it on for the first time this year. When I started it, the compressor wasn't kicking in so I put my gauges on and she had about 110 lbs. of pressure on the high and low side. The compressor should have kicked in. I checked the fuse in the glove box and under the hood. The both have 12 volts So I pulled the clutch relay and could not find any voltage there at all. None on either side of the contacts or the coil. There was no voltage on either side of the diode. The controls seem to work just fine. When I turn it to max, the blower blows even harder. The a/c button seems to be working fine with it's light and all. It seems the PCM is not sending a signal to the relay or am I wrong. Can anyone tell me where to go from here?
