I have doubts that what fixes his will work the same for yours.. It's marginally possible tho. I'm only guessing your 06 is a full size, in which case your system has a low pressure switch on the dryer that connects the HVAC controller to ground when the pressure is above the low cut-out pressure (normal operation). Then you have an A/C pressure SENSOR, a 3-wire sensor that tells the PCM exactly what the operating pressure is of the high side. Everything else is Class 2 Serial between the controller and the PCM. Your problem will likely be different. Have you verified the system pressures?
