A/c blowing hot air

(1999 Chevrolet Silverado 1500)
A/C is blowing hot. Have narrowed it down to temperature control. Compressor working. Lines are cold. Seems like the temperature control knob on the dash does not cause any difference in the air temperature coming out of the vents. What should I check now? Thank you!

The temperature door actuator behind the dash may have failed. If so a fault code should be stored in the a/c control module. Reading, diagnosing , and repairing the cause of any stored fault codes should get your a/c system back to proper operation.

Thanks a bunch Oakman, I've been trying to resolve this problem for about 4 weeks now and I've replaced the resistor, a/c actuator and I was wondering if I had to replace the temperature control system.
