What is the WOT relay?
What is the WOT relay?
Description. The logic module uses this relay to disengage the air conditioning compressor clutch when the throttle position is at wide-open (WOT). This provides maximum engine output when it is required. The clutch is allowed to engage again when the throttle is not at WOT.
What does it mean when your AC compressor does not spin?
It is an ominous sign when the clutch engages but the compressor does not spin. Changing the compressor clutch could be the only solution in this case. A bad AC compressor clutch needs immediate fixing. A delay can cause serious damage to the air conditioning system and the engine.
What to do if your a / C compressor won’t engage?
HOWEVER, if you cannot turn the compressor on, you cannot recharge your AC levels (grrrr). So you need to use a paper clip to bypass the relay switch and force the clutch to engage. You can then recharge the freon and re install the relay switch and it will sense more pressure and the clutch will engage by itself. Loading…
Why is the a / C CLUTCH not engaging in my Ford Ranger?
The A/C requires a enough pressure on the low side to engage the clutch. It protects itself in the event there isn’t enough R134. Put a gauge on the low side (the side nearest the coolant overflow/washer bottle) and see where it’s at.
What should low side pressure be on Ford Ranger?
See the Ford Ranger troubleshooting charts in here: ( http://imgur.com/a/xMUKH ). Notice the chart says low-side pressure should be between 20-50 psi, which means the compressor should shut off at 50 psi, and turn on at 20 psi. Your low-side (blue cap) pressure is rather high.
