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!
