Hi folks,
both my AC compressor and fans don’t come on with the AC switch on the fan speed control knob. If I connect the compressor positive connection straight to battery positive it does spin and the condenser becomes hot. I’ve just had it regassed after fixing a leak on the condenser and the auto electrician said it worked all fine and blew cold air. The only issue they said is that the system is running at very high pressure in idle hence i should only use it on the highway which is fine with me (I suspect the viscous fan needs a rebuild or the two additional fans don’t come on).
What I’ve checked is the following;
- both the high pressure and low pressure switch let current through. If I put a bridge on both plugs it makes no difference, compressor still stays off.
- 30-A fuse is fine
- AC light comes on with the switch. Fan only blows at full speed setting (speed resistor but that shouldn’t have an influence?)
- couldn’t find a designated relay for the compressor in the fuse box
I hope someone could point me in the right direction. It is a bit frustrating as I’m driving around Outback Australia in the summer now. Does anyone have a wiring diagram? I couldn’t find one online or in the Haynes manual.
Thanks in advance.
