truck came into shop for theft recovery, (stolen radio) customer installed aftermarket radio, wiring hell you can imagine. well had to replace complete dash assy. due to broken pieces on dash. replaced dash and and now when you start the truck it idles at 2000rpm and wiper motor just makes a buzzing noise the entire time. Didn't know if anyone had some information on this problem. Is it possible that the wiring harness needed changed over? Thanks in advance.
