Question about 1989 Chevrolet K1500
Same thing is happening to me on my 89 silverado c1500,
once in a while mine will make a clicking noise for a min or so. Tried cleaning contacts, checking wires and finally replacing the controller with two different ones from the wrecker with same result as the original. Any suggestions would be appreciated

Also, check the contact pads on the plug side and control side. clean them with a standard pink eraser and wipe clean. be carefull, it is very thin plating on the board. smear a very light coat of dielectric grease on the contacts and try again.

Usually if the controller becomes defective it will flash. It could be the wiring but if you have power to it then you need to confirm that it has ground. It will be under the dash, may be behind the pass. side interior panel below the dash.
