If air only comes out of the defrost that could mean the linkage assembly on the side of the suit case box is broken, happened on my truck but have no fixed it yet.

I had a similar issue with a 96 Suburban. Vents were stuck on Defrost and there was no heat.
I replaced the HVAC control panel and it fixed both.
