My 1995 buick lesabre custom heater control works when it wants to.It will
work but sometimes when you push the buttons to turn on the heat or a/c I
hear a clicking sound coming from somewhere behind the glove box and the
lights will flicker and then come on. The system will work for a while then
may turn off or blow through the vents. Do I need to replace the control
programmer or the control panel?

control panel is NOT the culprit. Have you looked behind glove box to see
if there's a relay back there? When one malfunctions, it sometimes has to
hunt for enough voltage to actuate the load-circuit and its points vibrate &
click. Describe symptoms to AutoZone & ask them to tell you if there is one
under dash and where it's located; if there is one behind glove box, I'd
try replacing it first. One brand they carry, Bosch, should be quality
mdse. & should cost around $10-$15. HTH, s
