A/C Unit on 1993 Buick Century

[smidge]

Have a 93 Buick Century that Compressor does not engage, was working fine and all sudden just stopped working. Checked the inline switch and it is ok. Can someone tell me which one of the relay switches operates the A/C unit. It has 5 relay switches, and just can't see paying close to $40.00 for a book to see which relay switch operates the A/C.

Sounds like the A/C oculd have leaked down. They have a low pressure switch which will keep the compressor from engaging if the pressure is to low. This is to prevent damage. So check you a/c charge.

Try this for relay info. http://www.autozone.com/N,4294880350...locsSelect.htm
