Air Conditioner Sub Harness - R32

[jm323232]

I'm chasing an issue where my climate control doesn't turn off even after hitting the off button.  Can't tell if these wiring joins are factory or the harness has been modified.  I don't think they would crimp a white/red wire to a black wire.  The other wires appear to be the same color.  There was blue electrical tape covering the crimped connections.

I have already replaced the Blower Amp with a brand new part and there was no change.

Without having checked the wiring diagram, visually they all look like factory style crimps. They use brass joiners and a small piece of electrical tape from factory

Have you seen the (readable) diagrams that GTSBoy posted up?

I did.  Great wealth of knowledge on here.  Haven't seen the brass joiners before so I wasn't sure. 

I'm going to do the diagnostic tests to narrow down my problem.  Could be the blower motor or the climate control unit itself.  The blower motor runs even if I disconnect the hi relay.  I will posts the results of the tests when I complete them.

At face value, if the motor runs with the relay disconnected it is probably earth switched and it is earthing out somewhere in the loom

Think you are right about the loom.  I was able to choose the fan speeds and get the climate control unit to turn off just once.  Moved the unit a little bit and the blower won't turn off again.  Below are the results of the blower motor system diagnostic.

Step 1:  When testing Hi-relay pin 3, the voltage is below 12.  Multimeter reading 5V. (Manual indicates faulty harness or faulty blower motor)

Step 2: Testing fan control amp pin 4 in self diagnostic mode.  Standard voltage for digital display values 41 - 46 should be 1 to 3 V.  My reading for display value 41 and 42 is showing 0V.  43 to 46 are normal. (Manual indicates faulty harness or faulty automatic amplifer)
