1992 Buick Skylark heater not working Sign In

I recently purchased a 1992 Buick Skylark with a 3.3L V6. I had to replace the radiator (which meant having to de-pressurize the A/C system), but my issue is the heater will not work. I can get a faint defrost, but nothing else. I checked the relays in the black box on the firewall and they checked out good, as well as the fuse in the fuse box. Coolant is at proper level. Kinda at a loss on what it could be. Any help would be great, thanks!

Do you mean an air temp problem or blower problem?

Might be Blower problem. I can't feel any flow from the vents.

Test all your fuses first, then jump power and ground directly to the blower motor to test it.
