I have 2000 rodeo, the window trim bunches up everytime i roll up the window and it is very annoying. I fix it after each time i roll up the window and it works once and then bunches up again not allowing the window to shut. How hard is this to fix and where can i get a replacement strip? Also, electric mirrors and rear driver side window dont work anymore, dealer said mirrors and window switch about $100 each to fix....can i get these cheaper anywhere else and how hard are they to fix by myself??
