Thanks for the reply but I already replaced the relay. When the relay is removed you can get a 12V reading on the terminals of the relay socket where the relay coil is supposed to be plugged even if the a/c thermostat and fan switch are disconnected.

try to check also the a/c power control module, I think there is something grounded. On the compressor relay, there is permanent positive and the signal is negative supply that coming from the a/c power control module.

..marami pong salamat..

Sir san po ba location mo? I'm also using converted bighorn, ganyan din po problem ko dati nung una ko nakuha ung unit, the problem is tinitipid po ng supplier ang pag convert sa aircon natin kaya mdyo poor quality ung bang tipo na umandar lang ok na. Try to check the following, expansion valve, comprossor and kind of Freon that is use in your unit. eto po kasi mga inayos nung mekaniko ko after nun satisfy na ko sa AC ko, kahit ndi na pa install ng ceeling evaporator ok na ung lamig abot na sya sa 2nd row.

One side of the relay coil is connected in series with the thermostat, a/c switch, and fan motor speed control switch. The common terminal of the fan motor switch is grounded and there is a + 12v ignition switched connection going to the fan motor, the thermostat and the a/c switch which all seems fine. However, I traced the other side of the relay coil going to a small black box labeled WL81 located under the glove box compartment of my 2002 2.9L XL ranger. I don't know what exactly this box is for but it contains a small printed circuit board about the size of a cigarette pack. Is this an engine control unit and could this be the source of my problem. Could anyone tell me what this black box is?
Is there a reputable auto a/c electrical shop that could readily analyze my problem and not do guesswork on my a/c problem.
