90-96 C68 ECC AC HVAC Restoration Kit

Restore your HVAC system and save!

The 90-96 C68 HVAC Controller Module

 

The 90-96 C68 HVAC Programmer Module

 

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.

 

This restoration kit addresses all of these problems!

 

Symptoms

  • The control unit display is blank, or the display shows "---"

  • The control unit operation is intermittent or locked up
