Restore your HVAC system and save!

The 90-96 C68 HVAC Controller Module (below)

The 90-96 C68 HVAC Programmer Module (below)

Over time, heat can cause the capacitors in your C68 Control Module and Programmer module to leak or dry out, and eventually to short-circuit. Protection diodes and communications transistors can be damaged by reverse or 24V jump starts. Age and pot holes cause the bulbs in the control unit to blow. Solder joints on the solenoids turn cold and solenoids stop working.

Update as of 3/25/2020:  The controller bulbs now include factory sockets installed.  These are new production as of 2020 bulbs and sockets!
