A/C relay question(w/picture)
Ok so my A/C went out yesterday. I tried searching the forum and I didn't find anything that kind of outlined this. So things I noticed. When I unplug or plug the pressure switch at the dryer the A/C condenser fan turns off and on. So I assumed the pressure switch is getting a good reading
I see that my Compressor clutch coil is not engaging since it's not spinning with the belt.
Checked my fuses #1 under the hood and #14 interior
So I decided to go to the rely under the hood. So I found relay with a snowflake icon according to the fuse box cover(I assume deals with the A/C).
I put my voltmeter up to it on 3 and 4. With A/C on it measure 13V avg. With A/C off and/or the pressure switch unplugged there's no voltage. So I assume this is the side that controls the relay to cause it to close or open the circuit. But on 1 and 2 I get no voltage and infinite ohms(indicating an open) with the car on and with the A/C switch on. So the relay has no voltage to control on 1 and 2. Would this indicate an open at the compressor? Because i've seen people talk about jumping with a wire to engage the compressor clutch coil. Which in my situation wouldnt matter since theres no voltage to jump. So does this point to my compressor or the clutch coil having an open?
