A/C help please

1990 Reatta, A/C light came on today. All new system one year old. Working up until this AM.

I discovered that one of the belts had started to chew itself up and a piece had lodged between the 

compressor and the clutch. after clearing it and checking the relay, the light is still on and the controller stays on 

vent. What could I have blowen? Is there a fuse besides the one in the consul?

Any Ideas will be helpful.

Thanks in advance.

Jon.

What 's "a whole new system" mean?

There's only one belt.

When the amber light comes on, it usually means the system's low on Freon.

Thanks Harry.

Everything has been replaced. (Whole new system)

He I supercharged so he does have two belts.

I am not an expert on the 90 system, but I would start with checking the system pressure then apply 12th to the compressor.  I know it is not the norm but I always like to eliminate major components before chasing wires.

If the pressure is right and the compressor runs when it is jumped you might want to take a look at the low pressure sensor/switch.

Do the 90s have the power steering A/C cut out switch?

Thanks for all of the replies.

What do BD27 and BD28 read ? Engine off they should read 29-31. Engine running AC on about 3 and 50.

 

BI08 is the low refrigerant switch.

 

If tripped, disconnecting the battery for about 5 seconds should reset it.

Thanks guys, it worked after checking the fuses I disconnected the battery last night and  the air started to work again.

Thanks again everyone.

Jon.
