Check fuse if you haven't already. water can be from heater core leak or clogged evap drain pipe. This usually does not affect the blower unless it's getting high. Can you take the blower out or at least pull the connector off it to see if there is voltage (use a test light). If there is no voltage, suspect your switch.

Please see my tip at http://www.fixya.com/cars/r6234839-doesn_t_heater_or_air_conditioner_blow . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

2002 grand caravan blower motor intermittent replaced resistor


in review
the fan speed resistor is new
you bench tested the blower motor
12 volts test ..only runs it at full speed
if cabin filer want changed the blower motor would run hotter

could be the motor brushes or bush/motor bearing when slowed
you might want to inspect the brushes and clean the dust out of the motor
if no better
does that have climate control ?
might be the fan switch itself or the earth isnt so good

2004 Grand Am Heater fan quit working, started loosing speed control then stop blowing all together.


Could be the blower motor or the resistor. The resistor should be behind the glove box. You can look the part up online to see what it looks like.

01 grand.prix ac fan switch only works on high. has a duel temp controller when you turn fan off the only way fan comes back on is to move the temp controller levers


Hi!!
When the Blower Motor Resistor (controls blower speeds) goes bad, the blower motor works only on HIGH SPEED. REPLACE IT.
BLOWER MOTOR RESISTOR Removal & Installation
  • Disconnect negative battery cable.
  • Remove right lower instrument panel insulator panel.
  • Disconnect blower resistor connector located behind right side of dash.
  • Remove blower resistor screws and blower resistor.
To install, reverse removal procedure
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa!!

I have a 2003 GTP and at times the heater fan stops working and now the display unit quits working and it says the fuel is low but I have 3/4 of a tank


I believe that these are two separate problims. The Heater fan stops working because the blower motor resistor block is bad. This is a common problem on the 03 Grand Prix. You'll need to remove the blower and replace the resistor block. The blower is under the center of the drivers onsole.

A/c heater fan no blow


sounds to me like the blower motor resistor, and if I'm not mistaken the resistor and the blower motor are located under the dash on the passengers side. the resistor should have a wiring connection and 2 screws attaching it to the blower case. The a/c and heater blower will not work if the resistor goes out. hope this helps you out a little. Best wishes.

Heater fan regulation


2002 Grand Caravan. The rear heater also has a resistor for the fan speed control.(3 speed) It is located under the rear passenger side plastic cover. You can take off the rear tail gate lower plastic piece and this will let you pull out the side panel. You can reach in and take out the two screws that hold in the resistor and unhook the wiring adapter. You do not have to take off the whole side panel as you can reach in from the back. The resistor unit can be bought at you local dodge dealer.
