I have a 40 pick up that someone wired with an after-market headlight switch. It worked good, now after I was near the dash wiring putting in a fan switch only the high beams come on with the dimmer switch. Any ideas,
Thanks in advance.

Only you have the ability to check if you have juice on the low beam side of the switch. If none, it's most likely the switch. If yes it's somewhere between the switch and bulbs or the bulbs themselves.

If you have a floor mounted dimmer switch check it, they do fail.

Normally the switch only sends power to the dimmer switch. The dimmer switches the high/low function.
