This is a common problem with the Blower Motor Resistor.
Disconnect the Battery and wait at least 2-mins to prevent a accidental discharge of the Passenger side Air Bag.

Remove the Dash-Glove Box. The Resistor is located directly behind the Glove Box on the fire wall, and is held on with two (2) 8mm screws.
Unplug the Resistor, remove the screws and it pulls-out.
Install the new Resistor, install the screws, plug back in, reconnect the Battery and recheck the Blower Speed operation. Re-disconnect the Battery (Air Bag!) and reinstall the Glove Box.

Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com!

A/C on caravan only works on high


There is a front-rear blower motor relay control that is involved in the circuits. This control module could be the problem. The blowers bypass the resistors to run on high speed.
You may have to get a repair manual with detailed wiring diagrams to trace the circuits.

I have a 1999 323i BMW. The AC doesnt blow cold (on cool days it blows cool temperature but not common A/C Cold Air, Hot Days it blows Warm/Hot Air). The heater blows warm air but definitely not common...


First things first.....You must have the air conditioning system hooked up to an a/c system machine and then checked for leaks and also read low and high side pressures. If there are leaks then low Freon (R134a) content and low refrigerant oil can cause the a/c system to not engage the a/c compressor which basically means you will not have proper defrost functionality nor regular air conditioning. Most shops, when working with your air conditioning, will install air conditioning dye to assist them in locating leaks and is the first step in diagnosing all a/c systems. Post the findings after thw

Heat and air condition only blow when the control is turned up to high position. And I even tryed replace the control panel.


this problem is caused by the blower motor speed control resistor, it is located near the blower motor, the resistor end goes into the air duct for cooling, replace this p[art and the problem will be solved. See pitcure below, the part is about $13

My air conditioning is not working properly. When


The blower motor resistor is causing the problem on the van. The location of resistor is behind the glovebox door. Remove everything out of the glove box and remove the glove box from dash. In doing so you will see to the left of the motor the resistor. Remove the electrical plug and the two screws holding the resistor. Installing is the reverse of removal. Hope this will help you.

I have a 1992 mercedes 200 E WDB 021 Saloon, it has 8 button air condition and I dont know how to use it. Control wheel on blue position but When I push the button (leftmost)which has a glass figure on it,...


The pulley on the air condition has to turn it has a belt on it. The Compressor engages to pre cool the evaporator. Most likely you have a blend door pod leak or leak in the hose or the sampler valve is bad. I would replace the sampling valve behind the glove box/air bag. As that reads the cabin temp and if it thinks the car is cold the heat will stay on because everything is automatic. All vents will blow cold when it thinks its hot and in addition to floor and corner dash center vents will blow cold when it works. If the direction of air is correct then the A/C system may have a leak or need a charge of freon.

My air conditioner will only work (as far as the blower) on high. Also, the button that you press for it to blow out regular air or air conditioning, goes on and off while I drive


the high position has its own fuse and relay.the blower resister needs to be removed .it's under the passenger need panel in the blower housing.you will see it will look burnt and smell that way if it is bad.you may need to get a blower resister connector from the dealer also.good luck.

The air conditioning,the blower fan everything stopped working, on 2002 Nissan Sentra. Does anyone have any suggestions?


One suggestion. Have you checked the fuses ?

I would check the AC or blower fuse to start with. If you have the drivers manual it will show you where the fuse box is. Typically there are at least two boxes to check. One in the Engine compartment and one in the passenger cabin.

Look inside the lid of the fuse box to see which fuse may apply to the AC circuits or the blower and check to see if they are blow. the metal link between the two posts that plug in. If the link is missing you need to replace the fuse with one of the same rating. Make sure you know where you took the fuse out from and put it back in the same slot if its good. Check all the main fuses if possible to see if any have blown and replace if they have.
