I'm working on a 2001 jeep grand Cherokee limited. The air conditioning only comes out on the passenger side and only heat on the drivers side. The vehicle has dual climate control and I found the drivers side blend door actuator is not responding. After replacing I found no improvement. There isn't power going to blend door. All fuses and relays are good. I did however notice that someone had cut and spliced some wires to the control head for the hvac and was wondering if you could get me a wiring diagram so I can check for problems.
