I have a headlight door that won't go down. It's the early style with the limit switches. I've disassembled the limit switch many times, cleaned the contacts and it will work for about 10 or do times, then stop. Any suggestions?

 

Year and model will help.

 

It's the early style. 82-84

 

Heres the limit switch. I clean the contacts and it works a few times and stops again
