My grandpa is having a problem with his 1999 Cadillac Deville. Whenever he has the A/C going, there is a clicking coming from the dash. No air comes out of the front vents, however it will come out of all the other vents (floor and defrost) and still blows out cold from the ones that work. He took it to the local stealership and they said it would cost $600 or something dollars to fix.They said it was some motor inside the dash that they would need to tear out the entire dash to get to. Does that sound legitimate? I never really work on Caddy's or A/C systems in general, so it's all Greek to me.

i had problems like that on a 92 deville and the dash had to be ripped a psrt to fix, it sounds legit to me
and on a 99 deville i had the blower motor went out (vert common) and it was like 300 to fix.

when a caddy has problems expect to pay ridic $$ to get it fixed. Not just labor, but parts are ridic also.

its prolly the blend door system (controls which vents get air) is it only a problem with a/c? if it doesnt matter heat or a/c then its the blend door system. if its just a/c then its got to be something to do with the "auto temp control" system

Yeah, it won't blow out of the front vents regardless of heat or A/C. The dealer said it was the "mode door" failing to open to the front vents, therefore needing to be replaced. I had a feeling if the whole dash had to be ripped out to get at the problem, then $500-$600 is probably about right.

you might not have to pull the dash...take a look under it and see if you can see the blend door mechanism....is it electronic controlled or cable? (digital temp display and buttons - or - levers and knobs)

Its a digital controlled unit, so i would assume it would have to be electronic. I'll take a look under there tomorrow morning, and see what I can find.
