Heater/Blower Fan Works Only On Full Speed

Post by **Gayno** » Sat Mar 02, 2013 1:38 pm

As above.

Fitted replacement fan from Newkid, but it only works on full speed.

I've seen this before in Rovers where the resistor pack dies, is this the same on the Prelude?

Where can I find it, or whatever the problem may be?

There must be one somewhere, as the fan only has 2 connections, so it must be controlled elsewhere.

Probably my original fan seizing cause it to overheat and blow. It works on full speed as that will be 12v passed through without using the resistor pack.

There's a part title "resistor, blower" number 7 here:

The wifes civic had this issue when I got it, I bought and fitted this....

You could ask them if they do a prelude one?

Not what I wanted to hear. Any chance you could chuck it in the post and let me know how much to send you? Also could you take some pics of it in situ so I have a reference point to see what I can do?

Exactly the same as I had to do for our Rover a few years back.

First item is a transistor rather than a resistor

Number 8 looks like it's the recirculation motor.

So let me get this straight, the resistor pack sits in the top of the box, where the fan sits underneath it?

If you wouldn't mind please, I'll send you another payment

Did you fit the motor from a UKDM or a JDM?

The UKDM (non climate control) has a 4 position resistor pack - the JDM (climate control) has a transistor which adjusts the voltage.

If you've replaced the transistor with a resistor, you'll only get the full speed.

Ahhh... Someone with local knowledge!
