172 heater

[DomP182]

While servicing my car I double checked by Googling which way around the cabin filter goes but noticed all the photos are different to mine. The big plug is just lying loose rather than clipped into the heater blower where there is no clip to hold it, there also an open socket with corroded pins on the blower unit itself.

Could it have been replaced with the wrong unit?

Any pictures

Any pictures

I'll take some later, it was bugging me that the plugs have nowhere to clip to to stop them rattling about

The big plug into the resistor pack you mean?

 

[DomP182]

Looks like this

 

[JamesBryan]

That's a weird setup 🤔

That's what I though, I think theres at least 3 cars making up my 172.

I wonder if its had a replacement from a non sport model, probably why my ac doesnt work too

Yeah it's definitely different to what I've seen on my 182 and others.

 

[DomP182]

The fans all work as they should and the temperature just not the air con

 

[william84]

Different to mines.
Does it have climate control?

 

[DomP182]

Yeah it's got climate control

 

[william84]

Weird it's looks like the heater resistor has nothing plugged in

 

[DomP182]

It is odd, the pins are pretty damn corroded on the heater resistor so I cant imagine them cleaning up. All the fan speeds work and the warm air is controllable just no ac

Here's a picture of 182 top box striped

As you can see that goes the left hole so is facing upwards.
Yours seem to go in side ways with no plug connected

 

[DomP182]

It's an early ph2 172 so could it be that they came slightly differently?

 

[william84]

Maybe. It should definitely have a plug in the heater resistor.

 

[DomP182]

But everything works heat wise and all fan speeds work so that suggests the heater resistor is working somehow doesnt it?

 

[william84]

Not sure.
The resistor I'm sure has to do with keeping a constant heat. So if set at say 19c it should adjust between hot and cold to keep it at 19c.
Also they are common for stopping the blowers from working so maybe someone has bypassed that part just a guess though.
Tbh this has me scratching my head.
If it's been bypassed that could be the reason you have no Aircon.
Top dash off and trace the wire from heater box to inside would be my suggestion.

 

[DomP182]

The aircon is because the system has no pressure in it but the climate control seems to work fine. I thought someone else might be able shed some light on it, Renaults hey, always entertaining!

 

[william84]

🤣
Yeah I replaced condenser dryer and pipes to bulk head seems to have done the trick think it cost about 20 used good condition though new o rings regas

By this I mean anything warm works

 

[DomP182]

Had a bit of a dig around today and found this plug too, what's going on with this lot then? Where should it plug in?

 

[MRBILLYUK]

Yours looks to have all the right bits but just looks an untidy mess. I changed my 182's pollen filter a couple of days ago and this is what mine looks like.

Mines a 172 so a bit of a different setup I believe, different plugs by comparison
