    97 SLS HVAC blower issue

    Hi guys. Im trying to sell my Caddy but recently I noticed that the heat/vent fan is not working. I can't sell it without that working. Can anyone walk me through a list of steps I could follow to find the problem. I can't afford to put any more money into it than I have to. It only has 80000 miles on it so i should be able to sell if the heat works. thanks. 97 seville sls

    Re: 97 SLS fan issue

    I changed your thread title to home in on the correct "fan" - these cars have at least 5 electric fans !

    Use the Cadillac Tech Tips in Discussions; Item Specific to look for threads on the blower. Study the sticky just above this - "How to pull codes" - your car has its own built-in trouble code system and the HVAC systems and electrics are all monitored. Get any stored codes and return to the sticky to decipher them using the link to OBD2 codes - write it all down and post it here.

    There is a tutorial in Tech Tips for a Deville (not sure about Seville), but it should be very similar.

    You can get the codes sitting in your own driveway with no help.
