It is impossible to regulate the fan speed. The poti is a double one with switch. NPN is one of the two types of bipolar transistors, consisting of a layer of P-doped semiconductor the “base” between two N-doped layers.

If you have no current in this wire, that is a bad sign for the speed control unit — but also make sure that you have checked that the small 1A fuse if so equipped on the fan speed control unit is OK.

I replace mine with 2n E made by On semiconductor also says Mexico Bm The hard part is finding a company that will sell you only one. Can you please post info on the donor new part Noticed that the potentiometer used is welded into a small board circuit with few bdy9. The original potentiometer is datasbeet with a switch to turn the system on and off on the lower end.

The shape is not oct the same but, with bry29 bit of work, the new trimmer can be fit in the old body. Now the bad news, whilst it seems difficult enough to get a double one with switch,there is no indication of the impedence on the Poti nor if it is linear or logaritmic type Aug 25, Switzerland Full Name: Since this one had a different shape than the original and no switch, took it also apart to gain access to the trimmer itself.


Datashset are six wires coming out the black box Having removed it from the small circuit board and measure it, it seems that one half is doing a proper job whilst the other half is not.

Sorry Mel no pics available. A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. 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. Mar 21, 2, New Jersey Full Name: Loose screw on my power transistor board fixed mine with exact same symptom.

First of all had to removed the control panel on the center console, well, actually have removed the entire dash and the console ‘whilst i was in there’ as Shamile would say Then i removed the entire fan control unit. Btw, the potentiometer in my car, has a switch dayasheet fully turned counterclockwise.

It is composed of semiconductor material with at least three terminals for connection to an external circuit. I have been wanting to do mine for a long time now. Otherwise, if you do some searches on terms like “base emitter” or “power transistor”, and you should bd2y9 some prior threads like this: They are OMP racing seat with 4 point harness.

By bending these tabs the two half will become an unit. The new one is simply a double linear potentiometer of Kohm impedence. Have, in the meantime, removed the dash to fix the usual leather shrink, and removed the potentiometer. Now the garage tell me is the fan motor which need to be changed. 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.

They look good also in red! If 1 is OK, connect an ammeter into the wire going to the base terminal. Decided, then, to dismantel the entire unit.

You can access this by carefully sliding a thin piece of plastic under the vent to push two tabs that release the vent- it then pulls out.

It will be the transistor sits in a heat sink that is riveted inside the air outlet duct below your radio. If you want to chat about how to change it out, Pm me and will exchange phone s Dennis.

Dennis Try this link http: Steve indeed my TR is an 87 model so quite an early one. A small current entering the base is amplified to produce a large collector and emitter current. Since this is a dash out job, and before entering into this new adventure, is there any way to check if the problem could not be in the potentiometer speed regulator??

Hi since was asked datasyeet user Melvok abt fixing of the potentiometer, have revisited this post. Steve Magnusson F1 World Champ.
