A/C only Blows on high

[want-a-fast-svx]

Just curious if any of you know why my a/c would only be blowing on high? It works fine just blows on high only no matter what its set on. Any and all help is greatly appreciated. Also im now having a airbag light come on???Is there anyway to trouble shoot that???Thanks again

there's an A/C diagnostic in the How To section.

are you saying that even if you press the low speed button it stays on high?

edit: the airbag system uses the same connector as used for ECU diagnostics in the kick panel, but different spots to plug in the connectors. look for reaper's site, he has a PDF file that descibes how to run the diagnostics.

did you find reaper's site & the airbag diagnostics?

i found the diagnostic for the airbag and am getting a code 12 :

12 Roll connector circuit is open, faulty CU, open
AIRBAG codes continued for 1992 SVX
circuit in main or module harness.

ANy idea what that means???
And i think i was getting a code 13 or 14 for the a/c...Ill try again and see what i come up with.
Thanks for the hlep thus far

if it's 13 on the A/C (sun sensor) you know this has to be tested in bright sunlight or with a 100 watt bulb on the dash? running the diagnostics in the garage is almost certain to set that code.

sorry, can't help with the air bag, never touched one in any make or model.

ok well i tried again to pull the codes to see why my ac only blows on high and now im getting a code 33/34.
33=Faulty Air Mix Door Motor Circuit
34=Faulty Mode Door Motor Circuit

..I have the a/c how to but i dont understand what all the stuff means when its saying to check it...Is this something i can just replace???If its not something extremely expensive i'd prefer to just replace it....Thanks for any and all help in advacne
