We have a 1990 DX that has a problem with the sidemarker control. Apparently this car was set up to run the sidemarker lights whenever the engine is running, (something I never liked). But now the sidemarkers don't come on at all while the engine is running. I can turn them on when the engine is off with the switch, but as soon as we start the car they go out. We have a chiltons manual that makes only one reference to what they call a "side mark control module".
If that "module" is the problem, I would really like some advise on how to locate an identify this little piece of ---- an just run the sidemarker lights with the regular switch........can anyone advise who has tangled with this same problem?

Thanx,
