Hopefully it will help other people with the same problems.
Well on the same day Saturday 16/09/07 I started to try and follow the wire diagram in the Haynes manual for the heater system with Aircon.
I started by removing the glove box and surrounding panels to gain access to the heater blower fan.
This was not to hard and do risk of braking anything.
1. I removed the blower motor and navigating it past the wire looms and brackets.
2. Tested the motor blower on the battery charger in the garage, spun up no problems.
3. So fault still lies somewhere behind this dash.
4. Located the resistor inside the blower aperture, if the reach in and twist it anti clock it will pull down and reveal the electrical connection.
5. The resistor contains 5 connections that pass the voltage across different tappings of the power resistor to give the speed settings 1 to 4.
6. Pin 1 must have had a poor connection at some point and was slightly tarnished crating a faulty connection on the spade terminal and on the connector plug also.
7. I cleaned the connections and added a little copper slip to the pin connections and refitted the resistor to the loom.
8. Refitted the blower motor and tested the system.
Result 2
I now have a heater blower in the car.
What is better i did not give Mike Thompson Stafford Ltd £650 of my money to fix such simple problem.
If the connection goes again i am sure if i was to cut the plug off the loom and solder the wires directly to the pins on the resistor i would get a 100% fix probably better than replacing the loom.
I have seen a few references to looms and 307 cars.
I think Peugeot are making money out of customers through poor product in some cases.
they should be trying to put a fix in place that does not cost £650.
Hope you enjoy the read.
