I have attached a couple of tests for you to do on the cluster. The problem is if it gets any detailed you need a couple pieces of test equipment to continue. But here is a quick test.
Testing and Inspection
As a quick diagnosis, the cluster will perform a functional check of the odometer display, transmission range display and warning indicators after the ignition is switched to RUN/START. If the cluster is not receiving any PCI bus messages, the cluster will appear non-functional and "no bus" will appear in the odometer display.
A self-test of the cluster can also be initiated by pressing and holding the odometer reset button and switching the ignition from lock to unlock. The cluster will then step through several displays for functional verification.
If the cluster is not functioning properly, refer to the proper Body Diagnostic Procedures.
If the cluster is not receiving PCI bus messages, refer to the pre-diagnostic test described in Body Diagnostic Procedures.
In order to diagnose the instrument cluster functions, a DRB III scan tool and the proper Body Diagnostic Procedures are required.
If the diagnostic procedure determines that a replacement of an instrument cluster component is required, refer to Cluster and Bezel REMOVAL and INSTALLATION in this section.
Check fuses 1, 7, 14, and 19. Check with an ohm meter though since it is hard to really tell if a fuse is bad just with the old eye ball.
You might try going to Auto Zone or O'Reilly's and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery, alternator and starter.
If the fuses are good and the car has not thrown any codes, you might have to take it in and let them run the test equipment on it to see what it exactly is. The money you spend on the check may be worth lots of time and hundreds of dollars chasing rabbits.
As for the HVAC - when you say it isn't working are you saying the AC isn't but the heater is? The blower motor blows good air inside but not heat. No AC. What exactly do you mean by it's not working?
Feel free to get back with us and we will try to answer more and please if you do, provide answers to the above questions to better assist you.
Also please let us know if this is just an Intrepid or Intrepid R/T. Also, what is the engine size in liters, 2.7 or 3.5 and give us the 8th digit of your VIN.
Please let us know if what the final fix was for your car so we can better assist others. Thanks!
