I have an 2001 dodge caravan with the 3.3, and 145,000 miles. The front blower motor only runs on high, and I can live with that. But I have noticed that when i have the power switch on to the heat/cool/fan console and have the fan switch on anything but high my headlights flicker ever so slightly.. so do you guys think its a bad motor or switch? or something else?
thanks

 

Here is a TSB that may help with the headlamps,and replace the fan blower resistor.

SUBJECT:
Flash: Digital Displays Flicker
OVERVIEW:
This bulletin involves reprogramming the Body Control Module (BCM).

2002 VEHICLES: VEHICLE THEFT ALARM (VTA) LAMP INOPERATIVE, VEHICLES
EQUIPPED WITH A (RAS) RADIOS WILL HAVE NO DAYTIME BRIGHTNESS,
AND THE BCM MAY NOT POWER DOWN WHEN THE IGNITION KEY IS TURNED
OFF. SB 08-019-02 REV. A NEEDS TO BE PERFORMED ON THOSE VEHICLES
WHICH WILL REVISE THE BCM SOFTWARE TO 04833855AD.**
SYMPTOM/CONDITION:
When the dimmer control wheel is set at maximum brightness, just below the parade mode
(daytime brightness) position, the Vacuum Fluorescent (VF) displays for the odometer,
transmission range indicator (premium cluster), Electronic Vehicle Information Center
(EVIC) or overhead console, radio and Automatic Temperature Control (ATC) may flicker

DIAGNOSIS:
**If the customer complaint matches the Symptom/Condition, the vehicle was built before
October 1, 2001 (MDH 1001XX), and the BCM software is NOT p/n 04833855AD, OR

EQUIPMENT REQUIRED:
NPN Battery Charger
CH6000 Scan Tool (DRB III®)
CH7035 General Purpose Interface Bus Cable (GPIB)
CH7000/7001 J1962 Cable

REPAIR PROCEDURE:
1. Connect a Battery Charger and set as close to 14 volts charge as possible.
2. Flash reprogram the BCM using the MDS2®, operating at CD 2121 or
higher, and the DRBIII® operating at software release level 55.3 or higher.
The BCM software must be p/n 04833855AD.

 

I dont know about the flickering headlights. But I do know what's wrong with the "one speed" situation. I had the same problem on my 01 Grand Caravan. It's a part, I think its called a "ballast", that is located behind the glove compartment door. Its a really easy job! Just move (or remove) the compartment door out of the way. The part is hooked up to one harness. Remove the single (I believe) bolt. And the part comes off. Replace it with a new one. This part is about $30.

I replaced mines, it fixed it. BUT now its happening again.

 

Master... so this needs to be done by a dodge dealer correct? and shouldnt be more than an hours labor, right?

fueled, thanks for the info I will try this fix!

 

The flash needs to be done by the dealer. The rest, anyone can do. The flash maybe 45 mins to an hour. The resistor if you have them do it maybe another hour.
