1994 Honda civic blower work but it won't blow heat or defrost just cooled air
You have a blend door issue - it is stuck in A/C mode. When you move the control knob from A/C to heat, it is hard to move? Does it seem to stick, or does is slide like normal?

1994 Honda civic has no heat when I swict from ac to heat

When you move the control knob from A/C to heat, it is hard to move? Does it seem to stick, or does is slide like normal? Also, have you checked the coolant level? Only do this when the engine is cold. Please answer each question and I will assist further.

The problem could just be the heater valve cable has slipped off the heater valve arm.

Slip the heater valve cable back onto the heater valve arm. Then cut yourself a 10 mm length of 3.5 mm vacuum hose (P/N 95005-35008-10M, H/C 2325058), and slide it onto the arm. This holds the cable on the arm nice and snug so it won't slip off.
