Firmly press and release the cruise control stalk buttons to ensure proper contact. Should problems persist, inspect the stalk for any physical issues and consider repair or replacement to restore optimal functionality.

Lost Memories and Re-calibration

A battery change can sometimes induce temporary amnesia in your vehicle’s cruise control, causing it to forget its pre-programmed settings. There’s no need to panic, though; what’s required is a re-calibration process. This step is crucial to jog the system’s memory and restore its functionality, ensuring your cruise control operates smoothly once again.

Here’s how to do it:

To recalibrate your cruise control after a battery change, insert the ignition key and turn it to “ON,” but don’t start your Chrysler. Identify the cruise control interface on the steering wheel or dashboard. Check your Chrysler manual for the precise button combo needed to recalibrate; this usually involves holding “Set” and “Resume” simultaneously for a few seconds and then releasing them. You should see a message on your instrument cluster or a blinking light associated with the cruise control system to confirm a successful recalibration. Finally, start the engine and test the cruise control. Ensure it engages, accelerates, and decelerates as intended.

Deeper Electrical Gremlins

In rare cases, persistent cruise control issues may indicate deeper electrical gremlins within the car’s system or specific components. This situation calls for you to seek assistance from a certified mechanic or dealership for a thorough electrical diagnosis. Such professionals will delve into the system, identify any lurking problems, and get your cruise control back on track.

Symptoms Of Bad Cruise Control Switch

Symptom 1 of a bad cruise control switch is when the brake pedal does not disengage cruise control, suggesting the switch may be faulty. Symptom 2 involves hissing noises coming from under the dash, where the cruise control switch’s vacuum system is mounted near the brake pedals; such hissing could indicate a broken switch or vacuum hoses. Moving to Symptom 3, if the cruise control switch/button does not work, failing to turn on or function correctly while cruising, it’s a clear indicator of a faulty switch or underlying wiring issues. Lastly, Symptom 4 highlights a blown fuse as a simple error to fix; the switch circuit or fuse may just need to be replaced to resolve the problem.
