a/c air conditioner problem.
 

I made mistake wire the battery switching + and -
for 10 seconds.
It blows fuse 16, 42.
One blade fuse that located on top of the battery.
I checked every fuses and changed if fuses looks bad even little.
Now, everything works fine but a/c

a/c compressor clutch isn't engaged when I turn on a/c.

The fans spins when I turn on a/c. No leak point.
I vag-com the car but no codes for a/c.

Any place I need to check?

Any ideas ??? I have the same problem, besides the blowing of the fuses

that's what I ve done so far since last year,
1. I checked both fan motors are working slow or high.
2. I changed coolant temperature sensor.
3. I changed a/c switch located on high port of ac pipe.
4. I changed fan control unit three times.
5. I checked all fuses.
6. I checked voltages that go to fan switch on radiator. both voltage around 11v.
7. I checked temperatures from climate control unit, all temperatures can be read find.
8. No voltage found connector that attached to compressor clutch even I set lowest desired
temperature.
9. If I wire compressor clutch with battery directly, cold air blow in to car.

I stopped here and build circuit with own switch and fuses, so if
I switch on manually inside of car, I can have cold air.
To prevent forgetting switching off, I wired a relay with air blow fuse, so I turned off the car, a/c is off even switch is still on position.

but I will start to find the problem when I have time.
I just don't have any now.
