1987 GLHS Power Module Failing

[mr b]

Hi guys and gals,
Can anyone tell me where to get a working power module for my 1987 GLHS?
I have tried all the usual vendors and auto parts stores but can't locate a working one.

Mine is going bad, as the other day the radiator fan kept running after the car was off and kept running until the battery died. Then it wouldn't stay running after jumping the battery. After I disconnected the power module for a few minutes, it charged up and ran fine.

Then a few weeks later, the car shut off for no reason while I was driving and wouldn't restart until I disconnected the power module for a couple of minutes and then reconnected it.

I am interested in used, or new as long as the power module is running.
