306 Heater / Aircon

[Rob]

The heater controls in my 306 have given up the ghost. The two knobs on the left don't work (they control speed and temperature), but the cable operated third knob (which controls the direction of the air) does work. The aircon lights don't come on either, so I'm guessing its some kind of electrical issue (typical Peugeot..)

The fans are blowing heated air, so theres nothing wrong with the actual heater matrix.

I've checked the fuses and they are fine, and I've taken the centre console out and checked the wiring, everything seems intact.

Anyone out there have any idea what else I could try next??

Some useful info on there about the air-con/heater system on 306's (links on the left side of the page)
It wasn't working on my 405 either, but I traced it back to the multiplug on the blower unit (it had fried completely) and the air-con ECU.

No real joy there but cheers anyway ryan.

I think I'm going to buy another heater controls unit off ebay and give that a go.

Have a check on www.aussiefrogs.com
There's a wealth of info on there

Scrob is it blowin air but not with much force?

Going too fast on the M1 is to blame .

Anto, the two left knobs don't work, the air coming out is always on hot regardless of where the knob is and I can't adjust the speed the air flows at. The knob in the right does work though and I can direct the air to my feet/windscreen etc. The two left knobs are electrically controlled whereas the one on the right pulls a cable, so it's definitely an electrical problem considering the aircon light won't come on either when the button is pressed.

Had this problem too.
Take all the fascia panels off the centre console.
There should be a white lever just below where the clock would sit.Flick it and that should be job done.
Ive no idea what moved mine in the first place but that solved my problem.

This however was on a phase 2 so not electronically controlled.Try it and see...

No lever on mine lad, all electronic..

Sounds like a heater resistor. I know they used to go on the Xantia's and the aircon one is way dearer than an non aircon In around £90 . Not too sure whether it'd be the same part as in your 306. You can sometimes fix them by re-soldering them. That could be one part of your problem fixed.

 

[Rob]

Where abouts is the resister found mate? Is it on the circuit board inside the heater controls unit itself?

Ive never done one on a 306 so im not too sure exactlly where it is but it is in behind the controls at the heater box. You might get at it from the passengers footwell if you get the glovebox out, but your has aircon and there ain't nuch of a glovebox to take out to get room to work. Get a mechanic to check it out for you if your not sure. Don't quote me on it being the fix for the problem but it's worth getting it checked out.
