1987 Cadillac DeVille - A/C Module Failure under hood, by Wales 1 at Wales Garage Corp
July 16th, 2008Blower module and compressor run throuh this part AC Delco #15-72530 this part has an aditional update that must be done at the same time that it is replaced. The harness kit is a PT 204 You will probaly have to order it special as most don’t stock it! Delco catalog 15a-100-06 Page 203 Says use 2-way conector 12101932 and 4 way 12058322 Thats great but when you order them no instructions are given on how to and what wires to cut! or repair. So we have divised a fix for the compressor side with a relay.
Cut # 204 wire blue and install relay contact #30 #87 30 to compressor 87 to good ground. 86 from module 85 to AC fuse Use a any bosch type relay with a good harness. We cut them off the scrap cars and this fixes the problem.
