#1: A/C Problem Author: MrrNoName, Location: UKPosted: Mon May 02, 2011 10:09 am ---- only fan speed 2, 3 and 4 function (there's no power on setting 1)
i think this is the blower motor resistor and have it on the list of things to get done
however ive now noticed that my air con only clutches in on position 1
so i can either have my compressor working and no fans (position 1)
or my fans working and no compressor (position 2, 3 and 4)
i switch from position 0 to 1 and i can clearly hear the compressor click in, and then hear it running, i switch to position 2 and i can clearly hear it click out, its the same for 3 and 4.
if i keep the compressor running on setting 1 for about 20 seconds with no blowers and then switch to position 2 the compressor clicks out but the air is ICE cold for about 10 seconds then goes warm again (because the compressor was, but now isnt running)
why would the compressor behave this way, is the operation of the a/c somehow linked to the bower motor resistor which has failed on position 1?
ive had so many problems with my 206 recently, its really starting to grind my gears! lol any help would be really appreciated, thanks Last edited by MrrNoName on Tue May 03, 2011 3:08 am; edited 1 time in total

Author: brad-morris, Location: BromsgrovePosted: Mon May 02, 2011 10:12 am ---- Air con may need re-gassing, as it has enough refrigerant in it with setting 1, but as you put it onto setting 2 its too much of a demand for the compressor so it cuts out for safety.
#3: Re: YET ANOTHER PROBLEM WITH MY PUG :( FFS AGAIN?!?! Author: MrrNoName, Location: UKPosted: Mon May 02, 2011 10:20 am ---- its ice cold and doesnt cut out when operating on position 1, it doesnt need regassing also the compressor works off of the engine, not how fast the blower motor is operating...

Take the car & your big head to an aircon specialist as you obviously dint want to listen to anyones help on here

Not in your case
I'd be looking at the rotary switch - this may be why the fan only works in positions 2,3,4 and if it is broken it migth only be sending the signal to trigger the air-con clutch is only being sent in position 1 as well.

Exactly what i just said, and for future knowledge the compressor is powered by electrics but needs refrigerant to run.

If it's low on gas it shouldn't run at all as the LP sensor will intervene. But I'm not sure the 206s have a LP sensor. It only tends to be more expensive cars.

Its a PSA Peugeot / Citroen product, it does have a pressure safety sensor

Author: MrrNoName, Location: UKPosted: Mon May 02, 2011 10:36 am ---- sorry lol that probably was a bit harsh, just had everyone all day saying it needs to be regassed (its just been done so doesnt) if the compressor works off of electrics why does it clutch into and draw so much power from the engine?

Ah right. I was only having this conversation with my dad the other day about air con as his is not working. He didn't think the 206 would have a LP sensor. Now I know something he doesn't

if it does have a lp sensor, this still doesnt mean it doesnt have enougfh refrigerant to run on setting 1, it just wont havbe enough to run with any bigger demand than 1
#12: Re: YET ANOTHER PROBLEM WITH MY PUG :( FFS AGAIN?!?! Author: MrrNoName, Location: UKPosted: Mon May 02, 2011 10:43 am ---- but i didnt think that the "demand" increased with blower speed, i.e the compressor is either on or off and its load doesnt increase with a higher blower speed, might be wrong though..?

Isn't the demand of the gas determined by the temperature control, not the speed of the fan? According the Mr BSI it does have a LP sensor, If it doesn't have enough gas it won't run at all. Last edited by Mike_XS on Mon May 02, 2011 10:48 am; edited 1 time in total

I don't think it does either. The blower speed only controls the speed of the air passing over the evaporator, of course the faster it goes across the less it will be cooled. The only way I could see it affecting the load on the compressor would be if there was a temp sensor on the evaporator.
#15: Re: YET ANOTHER PROBLEM WITH MY PUG :( FFS AGAIN?!?! Author: MrrNoName, Location: UKPosted: Mon May 02, 2011 10:49 am ---- thats not the problem anyway lol the gas is fine i guess the a/c somehow gets grounded through the resistor so when your resistors gone it doesnt operate correctly.
there are various threads on other sites about people who have a similar problem, power on 4 only, but a/c on 1,2, and 3. guess i'll get the resistor changed and see if that fix's the a/c as well.
i was just wondering if anyone knew why from previous experience etc
