Aircon Blower on and off

I found 2NG or equivalent will work well. It seems the problem is the potentiometer, or better say, one half of it. Have them in the car since datadheet years. Otherwise, if you do some searches on terms like “base emitter” or “power transistor”, and you should get some prior threads like this: I could find a double potentiometer of Kohm at the local electronic shop for few dollar.

Btw, the potentiometer in my car, has a switch once fully turned counterclockwise. Vdy29May 19, Whilst in there, and altought it was not the cause of the fan not working, have replaced the power transistor and, as a precautional measure, added a cooling fin to it pic 5.

At this point the blower work basically at full speed.

They look good also in red! Tks for any help on this matter Gianni. Noticed that the potentiometer used is fatasheet into a small board circuit with few components. After having open the black box, have unsoldered the potentiometer from the small circuit board and could measure the impedence on each half and spotted that the lower half had no impedence at all.


The original potentiometer is double with a switch to satasheet the system on and off on the lower end. I like having fan bcy29 adjustments eventhough it will probably blow out again. What I would do is: Also ask for a heat sink for it that fits over the top.

There are different control units for the TR and, unfortunately i was not able to get a used unit to match my car. Gianni, perfect description so Robbie, you should be able to order on line from any good electronics supplier. These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material.

Well, at least yours worked properly for a short whille with a new fuse. The new one is simply a double linear potentiometer of Kohm impedence. Produst description A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power.

The rotation shaft on the upper half, continue till the bottom of the case with a pin into which the the shaft of the lower half will insert. Wonder is something went bad there. Take off the trim panel to allow access for small drill or dremel to drill out rivets that hold the unit in the vent. It is impossible to regulate the fan speed. It is composed of semiconductor material with at least three terminals for connection to an external circuit.


They are getting covered in black Connolly leather to match the rest of the interior as we speak.


In contrast, unipolar transistors such as the field-effect transistors have only one kind of charge carrier. My fuse is good, so it cannot be the cause.

A small current entering the base is amplified to produce a large collector and emitter current. Hola’ just a short update. Because the controlled output power can be datasheer than the controlling input power, a transistor can amplify a signal.

Tks Kerry and Steve. Unfortunately, there are two different TR AC units and three different TR speed controls darasheet the wiring is a little different — and your report of having 6 wires on the fan speed control unit makes me think that you have the early type maybe with the built-in 1A fuse.

If you simply search BDY29 it will come up with Data sheets etc but I found it was not available so got an equvalent product. Darasheet 16, Sydney Full Name:
