    Cruise Control problems - PCM related?

    I recently bought a used 2007 Chrysler Town and Country. The cruise control works about 1 time in every 10 tries. I took it to my mechanic and he did an electrical check. Bottom line is that he says the PCM is going. $543 for the part, plus labor, plus programming. Is this something I should definitely do? What other things does the PCM control. I don't know if the cruise control is worth $750, but if other things are going to go out as well... maybe I should do it. Thanks for any advice.

    Tanman:

    If your problem is indeed the PCM or Powertrain Control Module, this is one of the few items covered under the Federal 8 Yr/80K warranty.

    You would need to have a dealer confirm the diagnosis, and if accurate the repair should cost you nothing, although I have been told that some states allow them to charge a diagnostic fee.

    On the other hand, if the issue is the BCM Body Control Module or FCM Forward Control Module, they are not under the 8/80.

    This is exactly correct. Take it to the dealer. You may have to pay a diagnostic fee if it is not the PCM... but that is worth the risk seeing how if it is the PCM it will be free (if you are under 80,000 miles).

    Went to the local Chrysler dealer yesterday and dropped off of the van. They confirmed that the problem with the Cruise Control is indeed the PCM and it will all be fixed under the 8yr/80,000 mile warranty (I have 72,000 on the van). So that is excellent news. The part is not in stock but should be in some time next week.

    They also gave me a free "courtesy inspection" (to drum up more business?) and suggested that I:
    • have a tune-up done
    • have ATF filter service
    • have induction and throttle body service
    • have something done to the sway bar links and bushings

    The van seems to be running fine, so my inclination is to not be too concerned about these things. Instead I will ask my normal mechanic about them next time I see him.

    thanks again,
    Todd

    At 72,000 miles, a tune up is probably not necessary, but as a firm believer in maintaining the 41TE transmission, a fluid change wouldn't hurt. As for the throttle body and such, the 4th gen 3.3 and 3.8's are known to get filthy build up there very quickly so it's probable that it indeed needs to be 'serviced' or cleaned. Also, the 4th gen. van's are known for sway bar bushing wear and sway bar link failures. Is there any clunking, whether light or heavy, when going over bumps?

    From what I see at work, I would say all of that is necessary... except for the plugs. They are not due till 100K.

    And I am glad it is going to be repaired free for you. The 8/80 warranty is a good thing.

    Yep, they are looking for your business. Why don't they follow the vehicle's Maintenance Manuals?
    Tune up at 72,000 miles: That's earlier than your maintenance schedule says. Same for the transmission service. Not necessary, but won't hurt anything other than your wallet.

    Throttle body cleaning seems to be a common money maker. I have never had the throtte body cleaned on my Van. Then again, I don't have an EGR Valve to dirty it up.

    Sway bar links: They last a long time and they don't wear out in pairs either. They likely have more miles left in them.

    Sway bar bushings: They don't last so long as the links. A loud clunking noise when going over small bumps says a sway bar bushing is worn. They don't go in pairs either but may as well replace both bushings at the same time. I tend to replace the passenger's side first. The other side last much longer (my experience). As to which side the noise is coming from? That can fool you.

    I disagree. Following the severe schedule, transmission service is recommended at 60,000 miles. And cheap as fluid is... and as expenisve as transmissions are... I'd do it. Heck my 10 only has 45,000 miles on it and I'm going to have it changed next oil change. Again, fluid is cheap. Transmissions are expensive.

    And as much as a fuel induction service helps start-ups and how the vehicle runs, I usually have mine done very 50,000 miles.
