GMC C1500 CLICK PROBLEM

1988 GMC C1500 • 128,000 miles

Electrical climate control module. Since april this year when I bought this truck its happened 5 times it swaps from floor defrost vent ect and even off and clicking everytime it changes and when it goes off the lights go out on it and sometimes flicker. The hot and cold settings and the fan speed are not affected unless it goes completly off. I have replaced the module didnt seem to fix it. So im thinking maybe a bad ground and suggestions?

Connector, conductor, component is a good way to look at the troubleshooting process. A bum ground is certainly a possibility.
