Default a/c problems with 1995 GMC Z 71

New here and sure hope someone can help me with my ac problems. Ac is working, but not that well. Blower seems to cut out periodically. The temp coming out of vents is 39 degrees. Just doesn't seem to have any pressure. The one weird thing is if I put pressure on the control panel in the dash, it sometimes will speed up.

What Ive checked and replaced:

Resister
Freon has been checked and recharged.

Any idea for a very hot dude living in Colorado in a heat wave

Thanks!

If applying pressure to the control panel makes a difference I would start there. Pull it out and check the connections. Those panels have been known to go out.
