#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

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
#16: Re: YET ANOTHER PROBLEM WITH MY PUG :( FFS AGAIN?!?! Author: Mike_XS, Location: SouthamptonPosted: Mon May 02, 2011 10:52 am ---- It could be a fuse. My car did some really odd things when the fuse protecting my radio blew. As in the radio would only come on if the interior light was off and the engine was revved....

the higher the fan speed the more the refrigerant will "cool" so to stop it from not meeting its demand the compressor works more to circulate the refrigerant keeping the temperature down. Thats how refrigerant circuits work on the systems i work on.
Do these compressors not modulate?

Author: macca1411, Location: Westhoughton, LancashirePosted: Mon May 02, 2011 11:48 am ---- Seems like you have already decided what the problem is from reading on other sites, so why bother asking on here. People are telling you what they know, if you already know better, then why ask in the first place.
#19: Re: YET ANOTHER PROBLEM WITH MY PUG :( FFS AGAIN?!?! Author: MrrNoName, Location: UKPosted: Mon May 02, 2011 11:54 am ---- incase someone had already had this problem and it was something other then the resistor.

If the gas has just been done, take it back to them and tell them that since they touched your aircon, it hasn't worked. They are supposed to be the experts.

Other people have given you advice, but you still harp on about the resistor. Change it, see if it solves the problem, and if it does, happy days. If it doesn't you might start listening to peoples opinions on their experiences and knowledge, rather than things you have read elsewhere.

Indeed if it does fix it post on here for future reference for everyone else. If it is your air conditioning then get someone who is F-Gas qualified to the new regulations, as the garage before obviously wouldnt of been if it is to blame.

Compressor clutch is electric, compressor is still engine driven - clutch is only engaging in positon 1 on your car - hence sort the electrics and there's a fair chance the clutch will say engaged in 2,3,4 as well.

Wasting your time mate, OP hasnt bothered with any of the other useful asvice they have been given
#24: Re: A/C Problem Author: MrrNoName, Location: UKPosted: Wed May 04, 2011 2:26 am ---- thanks stevesey, if the clutch is electric it makes sense to check the electrics first etc because when the compressor is clutched in it works fine so it probs is a clutching in problem.
oih MrBSI lol, its not that I havnt bothered, ive already done the previous advice thats been given before it was posted, i appreciate everyones help
even yours
#25: Re: A/C Problem Author: MrrNoName, Location: UKPosted: Wed Jun 29, 2011 8:54 am ---- Final Update:
It was indeed the blower motor resistor stopping both the blowers and the air conditioning from working. I purchased a new one from pug (about £20) and fitted it to solve the problem. Upon removal it was obvious that the old resistor had blown (one of the coils had broken)
I found fitting the resistor to be fairly easy and followed this method:
1. Unplug battery
2. Remove glovebox, first the lid (unclips) then the screws (6 screws around the outer edge, 1 hidden on the inside top of the box) then the box pushes down and out
3. The blower motor is located to the right hand side behind the glovebox. unclip the plug from the motor, then turn it 1/4 CLOCKWISE. it feels very stiff but suddenly unclips and comes loose.
4. Look into the pipe and you will be able to see the silver resistor attached to the top. Reach into the intake pipe and turn the resistor to free it from the pipe, then pull it into the pipe and unclip it from its plug (the hardest part).
5. Plug the new resistor in (also difficult with 1 hand) and put it back into the top of the pipe, then refit the motor by turning it 1/4 ANTI-CLOCKWISE.
re-connect the battery and all blower settings and the air-con should now work (mmm icy cold )
This procedure worked on a 1.4 (Y) reg 206 and was far easier then attempting to use the air recirculation pipe (found it way to small for my hands to get in) but may be different for other makes and models

also the compressor works off of the engine, not how fast the blower motor is operating...
i guess the a/c somehow gets grounded through the resistor so when your resistors gone it doesnt operate correctly.
