Default A/C / Heater slinoid pack issues

I am having some A/C issues with my 96 CE LT4, and my GM dealer CANNOT locate the Heater and AC Solinoid pack, part # 19151964... Anyone know where I can find one? A replacement? or ????

A Forum member suggested White Racing Supplies, sent an email and received a response: ** The part is available $597.00 exchange, + $400.00 core charge and $18.00 to ship........Need A/C in Central Texas, but $600.00 ++ WHEW.... What's A/C worth these days in a C4?

The part you're talking about is called an "HVAC programmer". It was used in other cars, mainly Cadillacs, so there's a fair number of them available.

Do a Google search on the part number and you'll find multiple options.

do the flea bay search in fleabay motors. You will finds dozens new and used...at normal human being prices...NOT Stealership rate.
programmers are a common part of the opt C-68 elect a/c system. Any high-end GM car since about 1985 had this as an option. Caddys and Vettes at first, many others later on.

This is probably what your problem is.

With all the above posts.

However, never really heard what the exact problem was.

For all I know the 3 way check valve under the hood could be bad causing no vent control.
