jndnaps Posted May 12, 2004 Report Share Posted May 12, 2004 I have a 91 Seville and the A/C only blows through the defroster. I can't find any vacuume leaks anywhere, Not under the hood or the dash. Anyone know what else it could be? Thanks, John Link to comment Share on other sites More sharing options...
justgreat Posted May 12, 2004 Report Share Posted May 12, 2004 i just had the same problem on my 90 seville...same condition: would only blow out the defroster vents...turned out to be a rod that had deteriorated inside the dash...operative word?: INSIDE the dash. one easy thing to check; undue the t fitting next to the firewall and make sure you do have vacuum from the bottle up front. jackg 90 seville 94k Link to comment Share on other sites More sharing options...
67coupedeville Posted May 13, 2004 Report Share Posted May 13, 2004 Hey hey, I just had the same problem with my 1991 Fleetwood. I would check the relay under the hood for the cooling fan. My relay was bad, I changed it and everything started working, I was so stoked . Hope this helps. Spence Link to comment Share on other sites More sharing options...
