I m having some concern w/my hvac control head. Diodes/lamps blink when on all controls seem to be operating normally/working. Any ideas? thanx

Try pulling codes. Press both OFF and DEFROST, then release and press AC (or VENT) within two seconds. If it reads anything other than 88 there is a fault.
