RE: 528e Problems

Bjorn,

  Have you tested the wires going to the compressor to see if you are
getting juice and good ground?

There is usually a high pressure and low pressure switch in the lines
also, look for the high pressure one around the dryer and if there is
a low pressure one it may be behind the compressor. Follow the AC lines
and look for wires connecting to any sensor, you can jumper the wires
together with a paper clip and see if the sensor is the problem.

Good luck,

Dave Orr

My air conditioner compressor will not kick on when I push
in the AC button on the climate control console. The blower
simply runs. I made sure it was charged up and I was able
to have the compressor kick on by running a hot wire from
the battery to the compressor, and hence it would cool. I
replaced the compressor switch and same thing still, with
the exception that it lights up with a blue light. Anu
suggestions what it could be? Perhaps the AC control relay?
Where does that animal live?
