05 JEEP TECH QUESTION

Several hot summers ago, in my 05 Ram, the interior AC fan stopped working. Next time I drove it it worked. This went on for a week or so until it finally quit for good. This should be simple I thought. Parts weren't too expensive and I wanted it fixed like right now. Got a new resistor, fan motor, and relay, thinking that should cover it. Wrong.
Turns out, I learned from youtube, it was the ignition switch. Not the key cylinder but the electrical box that the key cylinder plugs into and switches. It's a little, sealed plastic box. Nearly $200 from Chrysler. I opted for a cheaper one from the chain parts store. Well that one lasted about two months and gave up. Time to pay up for factory piece. Put that in and been good for several years.
I don't know if yours could be a similar issue but maybe youtube has some info.
