High Beam issue

[mikey531]

I went on vacation for 2 weeks and left my 1969 GMC C-1500 truck sitting in my garage. I went to open the hood and it was hard and wouldn't stay up, one of the lift cylinders on my billet hinges stopped working. Ok I called and have two new ones coming. Then yesterday I was checking my lights and turned on the headlights low bean and lights all worked hit the dimmer switch for high beam and low beam went out and the high beam didn't come on ! I bought a new dimmer switch no change. I have been chasing wires from the bulkhead to everywhere they are supposed to be. Nothing. The light switch was new 5 years ago and everything worked 2 weeks ago !!! Where do I go next? I think my truck may be mad at me.
