Hi all. I have a 1991 S10 4.3L and recently replaced AC compressor, accumulator, and accumulator switch. AC worked great for a year but both AC and heat went out completely a couple of months ago. Heard hissing from the dash, so I pulled the control panel and found a broken clip on the vacuum connector. I put in a new control panel that I got from eBay, thinking I had found my problem. Now AC compressor will kick on (it wouldn’t before) but nothing blows from any of the vents. Did I get a bad control panel from eBay, or is this something else like blower motor or blend door actuator? I checked the vacuum lines that go to the actuator and they have vacuum when ac or heat is switched on.
