Unfortunately he is a couple of states away or I would check it. It's a 1999 Jeep GCL with a 4.7. He said he checked the fuses and they were good. Has anyone had this happen and if so what did you find? Thanks

Is this your problem? I have no idea. 1969 Dodge Super Bee A12 (440 Six Pack, 4-speed, Dana 60 4.10) 1972 Plymouth Road Runner (400, 4-speed, 8.75" 3.23) 1974 Plymouth Duster 360 (360, 4-speed, 8.75" 3.23)
