05 GMC Sierra something electrical.

[GMC Sierra guy 92]

My door ajar light comes on. Lights dim out inside. When I smack the dash they come back on then out again. When trying to roll window down door ajar light comes on. If I push on the structure of my light switch the lights cut out. Help! Anyone!

Check battery connections and all body grounds to begin with
