SOURCE: where is AC clutch relay located?

Check the A/C pressure in the line, you should have 100-105PSI with the engine not running and if you have less then 45 PSI in your system. The A/C will not activate to ensure the compressor does not seize when the clutch activates.

Thank you for using Fixya and good luck

SOURCE: AC compressor clutch not engaging. Fuses ok

sounds like lack of gas pressure,take it to specialist and and get it recharged to the correct weight of gas,it is positivly dangerous to play with this because the A/C uses high pressures and can cause frostbite in 2 seconds when trying to refill with these boy racer silly aftermarket top up cans.THESE SHOULD BE BANNED WORLDWIDE

SOURCE: ac relay for f150 fuse box diagrams

If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :
https://www.fleet.ford.com/maintenance/owners_manuals/default.asp

The AC clutch solenoid is not in the fuse panel, not sure what relay is AC. There is a Blower motor relay, but this is only if the blower motor does not work in AC, vent or heat.

There is also the Blower motor resistor, but this is usually the blower only works on high, the other speeds are not functioning

All newer models have electric fans,you have sensors and relays that tell the fan to turn on and off,you can test if your fan is dead or your sensor or relay.from your fan follow wire until you find a connection plug,usually about 20 inches from fan. disconnect plug and run two jumper wires to your battery. this will tell you if fan is problem. continue following wires to find sensor, use test light when engine is running and getting hot to see if power is making it to sensor.if it is your sensor is not sending power to fan. if no power is making it to sensor, check fuse box on firewall of engine compartment for fen relay some models have 2. Or you can hook the fan up to constant power when car is running via the fuse box under dash, or hook fan up to a toggle switch mounted to your dash, either way you need to run new wires from your fan

    Some cars have a thermostat that tells the fans when the water temp reaches a certain temp then the fans start. Or the relay that starts them could be bad. You may find the relay and switch it with another like it and see if that works.

    Cooling fans wont come on 1992 nissan maxima


    To check power turn on AC if fans work it is the fan thermostat. I not then it is electrical fuses (dash under radiator overflow, next to battery) or check plug on shroud for corrosion.

    Fan still doesn't work.


    You may want to trace that relay power wire back. There may be a fuse under the dash that supplies power to it, and likely another in the distribution center. I'm fairly sure the pcm supplies the ground signal to the relay.

    Dashboard wont light up


    So, this is not a 2000 Hyundai Sonata? I used to own a 2000 Honda Civic and I believe those lights get power from a fuse inside the fuse/relay panel located on the driver's side under the dash. Check all your fuses. If all fuses are good, you've got a wiring problem - check for power & ground at each bulb. Obviously, if you don't have power to them, it's a power distribution/wiring issue. If you do have power to them but no ground, it's still a wiring issue.
