Peugeot 106 1.1 heater fan problem

[Mikespikey]

Hi everyone,

I have a 2001 Peugeot 106 1.1 with air conditioning, and I’m having a strange problem with the heater blower fan.

The fan behaves as follows:

* Position 0 (OFF): Fan keeps blowing at approximately speed 3.
* Position 1: Same speed as position 0.
* Position 2: Same speed as position 0.
* Position 3: Same speed as position 0.
* Position 4: Fan runs at full speed.

So basically, positions 0, 1, 2 and 3 all give exactly the same fan speed, while position 4 works at maximum speed.

I’m trying to figure out what could be causing this.

Could it be:

1. A faulty blower motor resistor or speed control module?
2. A faulty heater fan speed switch/control panel?
3. A problem with the blower motor itself?

Has anyone experienced this exact problem on a Peugeot 106, especially one equipped with air conditioning?

Also, does the entire dashboard need to be removed to access and replace the faulty part, or is there an easier way to reach it?

I’d really appreciate any advice, experiences or repair instructions before I start taking things apart.

Thanks in advance!

If you enter your vehicle details in this site you should be able to find a wiring diagram for your fan system and work from there:

I suspect you may have a short circuit across the fan switch contacts but that's only a guess. Good luck

It has all the symptoms of the heater fan resistor failing, it controls the fan speed. I had the same issue on a Mk1 Focus many years ago and a new resistor cured the fault.
