the climate control in this vehicle is/was rather complex. This was one of the first years that tey went to computer controlled climate control and yes, they did have problems or glitches from time to time. One thing that developed very common was the blower running all the time. In most all cases, the ECC power module failed. I suspect this is where your problem lies. this module can? affect other items like fuel data display etc but i can not confirm 100%. I would start by replcing the ECC power module or some call it the blower control module located under the hood, near firewall, passenger side on top of the heater case. You can also unplug it to stop blower. I can not rule out the BCM ( body computer) but more common was the ECC module. The BCM is located on top of the heater case under the dash. To be 1005 sure, a shop can run through a series of diagnostic checks to determine what is at fault. By experience, the blower module has been the problem at least 90% of the time

I have a 2003 Town and Country mini-van and I lost power to all my ... In addition to this my wipers, headlight controls, blinker controls, power door locks, and A/C/heat controls are out as well. The odd thing is that the power windows work, the power sideview mirrors work, the radio and ceiling lights also work.

The blower resistor is the most common thing to fail on these. Mounted under the dash on the passenger side, behind the blower. As far as no heat, It could be the heater core, the blend door motor, or the controller. My guess on that would be the blend door motor. It is located in the middle of the dash, just under the radio. If you have a center console, you may be able to get to it from the side.

have you check your main relay it sound like it has blown

Have you checked the fuse? The blower fan has a resistor that controls the speed in the air box by the passengers feet. When the heater core was replaced, something could have happened to the connection or wiring. Not sure why the radio would be affected by the same thing, could be a coincidence or something dislodged under the dash. Start at the fuse and go from there.

REPLACE BUSTED FUSES

good be dimmer switch, but only if all dash lights are out,like radio heater control, cig light,if those still work then i would say its bulbs.

check the power connections at the starter and under the black cover on the passenger side under the hood on the firewall.........sounds like you have a corroded power connection

a bad fuse ...keep looking .....otherwise the main acc power/ or ground to all those dash areas has been cut or compromised...retrace your steps backwards
