Default headlight run on

A while back I changed a headlight motor and the new one had run on just like the old one. Sent it back got another one and have the same problem. Funny thing is that if I take the motor and plug it into the other side it works fine. Changed the modual and that was not it, any ideas?

Just needed the pucks easy fix. Look on youtube. You can get them in the help section at parts store. The are use for some regulators too.

What you describe is a common symptom caused not by the motor but by the drive mechanism. Inside the big plastic gear are three plastic pucks that disintegrate, causing the problem you are experiencing. ~$5.00 + time to replace. Lots of instructive info online.

I battled one for 8 months replacing everything twice, turned out to be a bent linkage, Stan from feebay replaced and adjusted it and it's worked great ever since.

Its not the pucks because if I plug the motor into the other headlight plug it works fine. Im thinking headlight switch maybe?
