2001 Grand Cherokee Ignition Switch Power Problem

15614 19
No matter what position I turn the key nothing happens. I thought my ignition switch was bad so I replaced the switch and still nothing. I found a switch diagram and it works. I checked the switch connector and no power. I checked the 40A fuse under the hood and the fuse is good and power to the fuse. What's between the 40A fuse under the hood and the ignition switch that could be bad? The diagram I have shows "Fused B(+)" to pin CAV 2 and 4. I have no power on any of the 6 connections on the cable plug.

Headlights, interior lights, instrument cluster lights, power seets, power locks work, starter, gauges, instrument cluster indicator lights, odometer, power windows, radio are not working.

Don't do the dual zone conversion. That system is not built well and will fail at the blend door and blend door actuator over time. It can be fixed with like parts but fails again. It can be fixed for good with the "heater treater' but it takes away the dual zone feature.

(I have a 69 Cougar 'vert!)
It is at KTL right now...


Anyway, as I understand it, the axle that the blend doors ride on over twists the plastic door, breaks the attachment to the axle and allows the rotation to go beyond what it should resulting in a couple of codes including #52 on the ACZ self-diagnostic and the HVAC vent defaulting to defog/defrost mode. I'm not a good reference though as I've purposely stayed away from them until I got my Overland. It's working now but was replaced by dealer previously. When it fails, I'll do the heater treater.

If you need your in-dash A/C box restored let me know. After restoring over 300 of them I know them inside and out...

My Cougar had no A/C from the factory. What are we talking about in costs to add it?

That HVAC system in the WJ will need some TLC in the seals and foam insulation that deteriorates as well.
