Default C68 controls inop

The display on the control unit just says --, no buttons other than defrost light up no response from car when buttons pressed just reverted to defrost. No codes from unit in diagnostic mode. Tried another controller same thing. Where should I start?

Try disconnecting the neg. battery cable for 15 seconds to reset the system. If this does not work, I can post the diagnostic chart for '92, yours might be the same.
