Default A/C cools under hood, but not in car - Climate Control

Hello everyone,

1994 Bonneville SSE

Does anyone know why my A/C works fine in the engine column but blows warm air (almost seems like heat) when I put the auto climate control to full A/C or 60 degrees. Whatever I do to the settings, spits out warm air. My mechanic said it was prb a computer issue of some sort and told me to goto the dealer. Any ideas?

Thanks for the help!

Drew

Do you have a SES light?

Do you have buttons or *****?

Does the temperature display on the climate control blink upon startup?

You may be low on R-134a. I would have it checked out by a good A/C shop.

You are low on R-12. You need to have the leak fixed and the A/C recharged by a good A/C shop.
