The flickering dash was the subject of a service bulletin. I've had this going on in my '02 Libby since it was new. I've pasted the TSB from another forum here. However, it sounds like replacing the multifunction switch didn't help your problem? Did you check the build date of the switch that was replaced (or get that info off the invoice)?<quoted text>
I have had a similar problem since I purchased mine in late 01. The dash lights will occasionally jump to the next brighter setting. While on the brightest setting without having the dome come on it would occasionally turn on the dome light while driving. I changed the dash lights to three clicks below the dome light and they just occasionally get brighter. The dealer replaced the switch after about 500 miles but the problem stayed the same. I think its the connections in the steering column and its too much work for the dealers to take the time and fix.

Trip Computer And/Or Radio Display And/Or Instrument Panel And/Or Overhead/Dome Lights Flicker
This bulletin involves diagnosing the root cause of the flickering trip computer or radio display and/or instrument panel illumination and/or overhead/dome lights and replacing the multifunction switch.
2001 - 2002 (JR) Sebring/Sebring Convertible/Stratus 2002 (KJ) Liberty
Some subject vehicles may exhibit a flickering trip computer and/or radio display, instrument panel illumination, and/or overhead/dome lights. This condition occurs intermittently but is usually noticed while the driver operates the turn signals or beam change on the left stalk switch. This condition will not adversely affect vehicle operation and can be temporarily corrected by adjusting the instrument panel illumination dimmer setting. DO NOT change the position of the dimmer switch on the multifunction switch prior to Diagnosis.
1. Physically check to ensure the instrument panel cross car beam ground is good. The left kick panel must be removed to see if the ground is loose.
2. Next check the dimmer switch output voltage with a DRBIII®. This function is located in: Body, Body Computer, Sensor Display, Dimming Level. DO NOT change the position of the dimmer switch before monitoring the voltage across the switch.
3. While monitoring the voltage, activate the turn signal and beam change and look for output voltage fluctuations on the DRBIII® and instrument panel lamps or trip computer display flicker. If the voltage varies more than 0.2 volts perform the Repair Procedure.
