My 99 regal ls heat/ac went out.Replaced the climate control it worked for a day

(1999 Buick Regal)
Everything worked perfectly on the test drive after replacing the Automatic control module but the next day no air. The control system lights up and I can hear the servos moving when I change fan/air flow/temp but get no air flow. I can also tell when the ac kicks in by the engine surge. Fuses look ok no other issues I can see except no fog lights but may be burnt out haven't check them. I thought the blower was replaced before I bought the car but have to check it. Have you heard of this issue hand found any common problems?
Much appreciated.

Can the manual control module be used where there is an automatic control module?

No; it will not operate the controls, manual controls are different.

ok new developement, fan and whole climate system started working and the headlights went off and on several times with in a couple miles of driving then stayed on the rest of the way home approx 10 miles. Could this be a loose ground wire someplace?

It sure could or a bad connection causing high resistance. Doesn't have to be loose.
