Heater Problems

[christurbo]

I posted this in someone elses thread but decided to create one for myself.

I dont use my 172 much but when I have recently I get in turn the ignition and the fan blows OK and does so as normal.

However...

..... If I park up turn off the engine, turn on the ignition on at about 5 mins[or more] later the fan doesnt come back on. It eventually does come back on when I am driving around 15 mins later. Again - if I turn the car off for around 5 mins and then turn the ignition back on again the fan doesnt come on again...

Hasnt anyone had this problem? i.e. intermittent problems not a completely broken fan/heater.

Everyone has mentioned resistor packs - but surely that would mean my fan would not work at all not intermittently like it is!

Could it be the motor/fan/etc. Will all clio fans/motors fit in my 172?

Id love to hear from people who have had this problem or have experienced/fixed it.


Happy New Year.


Chris :approve:

Connected to the immobiliser?

Hmmm - good thought - anyone>?

Im thinking it might just be the resistor though?

Check the air sampler fan up in the panel beside your interior light.
The are prone to dry joints and knackered motors.

 

[christurbo]

The interior light is in the roof!???

Whar car are you asking about Chris ?

 

[edde]

Heating systems yep are the same on them all from memory.

Check the resister pack but being as your cars got the aircon removed I'm not sure what has happened the aircon might be having a right trouble with it. Also check the relay.

Temperature fan shouldn't be an issue

 

[nelson182]

I had a new heat resistor on my 182 recently. A common problem apparently

 

[BrianR]

You lost me Edde, what car does Chris have ?

172 full fat with climate but its had its aircon removed well partially. Pumps condensor etc are all out not sure on the other bits I'd guess there still there.

Ah ! I wouldnt have got that from his post, sounds like the resistor pack then methinks

 

[christurbo]

Yes - I had the FF aircon removed - condensor - pump - pipes - etc, and had the Clio Cup alternator and bracket installed.

Yep - I think resistor pack too!

I'll have to order one up when I get a chance.... although my heaters do still work - just not intermittently! It would be a PITA if it was my everyday car!

It has made me think I should buy a heated windscreen and rip out the heaters!

172 and 182 FF are different to all of the others

 

[christurbo]

They have different resistor packs for a start.

After a long run today

The heater didnt work for the first half of the journey - but did on the second half.

However it started to sound like it was 'chugging' ... almost like a diesel car tickover.... I then turned the fan down to the first bar - it sounded like it was struggling then cut out, and wouldnt come on again.

Think its the motor????

Are all clio motors the same?


Is this what I need???:-

[christurbo]

^^Bump^^

 

[edde]

Check to see if yours is getting a power feed first if not then this won't be the problem.

 

[christurbo]

Yep - Im going to cross the 2 x black wires coming out of the resistor pack connection - if the fan blows then I know it is OK and it will be the resistor pack....

Are all clio fan-motor units the same? Because there seems to be 2 x types on Autotrader parts - 1 x for non aircon and 1 x for aircon.

What are the differences?

How easy are they to fit?

 

[christurbo]

Anyone?

 

[edde]

Never realy checked I'd guess there two typres the air con being the more powerful one since its got a radiator right behind it (the arocon one).

Easy to chnage though bit of a bugger getting the unit out. its all under the scuttle panel.

 

[christurbo]

I think my motor is sticking.

When I get chance Im going to join the live wires over to create a connection to the motor so that I can rule to motor out or not.

Then Im going to remove the motor and check for obvious problems - then order one up if I cant fix

 

[christurbo]

ALL FIXED!!!!!!!!!!!!!!!!!!!!!!!!!!

I dismantled the connections - tried to remove the motor and fan. Whilst doing this I gave the motor a couple of taps with a small hammer, just incase the motor had stuck. I cleaned the connections - then reconnected it all up and Viola!!! Its Alive!!!!

Cost me £0 to fix!!! Thats a change!

I have now vaselined all connections and sprayed WD40 everywhere and made sure the scuttle is flush with the windscreen.

Cheers for the help - those of you who tried to help.

lol

Cheers Brian - I have a nice cold stella sitting next to me as we speak

Thanks for the info bud




BTW - love hammertime metaphore

 

[edde]

Well done.

Being looking at this today when I've been more awake theres two seperate fan types the air con one different due to its design in the heather box. Motors can be bought seperate.
