Cadillac Jim Posted October 11, 2006 Report Share Posted October 11, 2006 Could you get the diagnostic codes and post them here? The way to get them is on this page: http://www.caddyinfo.com/readingcodes.html From what you say without the codes, I would say that your HVAC motor is bad. There is a limiting resistor for the lower blower motor speeds that could also be bad but that's rare. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

PAUL T Posted October 12, 2006 Report Share Posted October 12, 2006 Check the fan motor connections. Make sure your spark plug wires are not within 1 inch of the fan motor. They will fry your fan motor. Link to comment Share on other sites More sharing options...

Cadillac Jim Posted October 12, 2006 Report Share Posted October 12, 2006 A compressor clutch short would pop another fuse or breaker, not the blower. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
