I've read that the control panel for earlier Malibus (99) had a problem with the heater control panel that caused the A/C to kick on and off (stays off for while when you want it on until you mess with the fan speed.) I've also read that changing the control panel out for a new one doesn't necessarily solve the problem for long since it is a production flaw. Yes, the freon levels, pump and relay are good to go. This is an electronic problem that has dogged me for years. Anybody deal with this before?
