A/C Button Question

I have a question about the blue snowflake air conditioning button. If either the blue button or the orange recirculation button illuminate when pressed does that mean there is a problem with the AC system? Or are the button supposed to light up all the time? Sometimes the button flickers when initially pressed on.

The reason I ask is that I finally converted my AC on my 1986 325e (325i engine swapped in) from R12 to R134 and fuse 20 keeps blowing and the condenser fan does not turn on either and I was wondering if the lights mean anything by being on. FYI, the AC system was vacuumed down, and does have a full charge of refrigerant.

Thanks

The A/C button is supposed to light up blue when the A/C is on, The re circulation button lights up orange if the recirc function is on. They are on when depressed.
The aux fan not turning, possibly a bad motor?

Thanks man, I appreciate the reply.

Im going to jump power to the fan to see if it will power on.
Im wondering if my motor swap wiring has anything to do with that fan not coming with the AC.
I know that when my car had an eta motor there were two temp sensors on the driver side of the radiator and when I swapped the "i" motor in the new radiator only had one sensor on the passenger side. I thought I had rewired the fan sensor properly when I went from two to one sensor but maybe not. I remember I couldnt find much one that part of the motor swap as far as the radiator sensors where concerned.

Ill have to do some more electrical testing with the wiring schematics in hand this weekend during the morning. It was 119F in Phoenix today.

Download the wiring diagram for your year BMW and a 1989. Just compare the wiring of the two sensor system of your 1986 and that of the single sensor system used on the 1989. The electrical wiring diagram books also have test/checks for your car's AC system. Good luck
