Car Forum / Peugeot Cars / June 2005Air Con
Hi OK, this is annoying me now. I had my air-con regassed not 12 months ago, and it has never been right. It blows warm. I called up the guy again and he came round. Attached his meter and there is no shortage of gas! No leaks either. He has emptied it and regassed it again, but still blows warm?! Anybody got any ideas? Fuse? Belt? Etc. Its a yr2000 406 HDI estate. TIA Oli Oli wrote in message ... >Hi > [quoted text clipped - 11 lines] >TIA >Oli So your air con expert does not seem to be much of an expert then? You will need to check the rest of the system. Does the clutch cut in an out, if so is it quickly(bad) or stay on and off for periods of minutes(good) Have a look for a pressure switch, possibly near or on the drier. Mine (405) gets corroded contacts and a few pull off push on cycles of the connector. Locate the all controlling Bitron module. Again try the connector trick with this. Check the temperature sensor in the fresh air intake. If this has failed or is telling the control system that the air temp is below about +4 C then the aircon is programmed to shut down. One more thing to do - Get yourself another aircon man. I just can't credit any specialist like this leaving you without a working system and as a minimum referring you to someone who does know what they are doing. Good luck Bob > Oli wrote in message ... >>Hi [quoted text clipped - 39 lines] > > Bob Thanks Bob. When I press the button on the console in the car, I hear a click in the engine bay - I assume that this is the clutch kicking in. Where can I find the pressure switch? Also, I have located the temperature sensor, but how can I test to see if it is faulty? TIA Oli wrote in message ... >> Oli wrote in message ... >>>Hi [quoted text clipped - 46 lines] > >TIA OK so the clutch sounds like it is working. I dont know where the pressure switch is on your car. On my 405 it is on top of the drier by the side if the radiator but there are no rules as to where pug will have put it. Trace the pipes and you should come across it. Look for pipes in and out with say about 4 wires going to it. Connect a volt meter to the temp sensor. Blow on it with a warm hair dryer, then put an ice cube on it. the voltage should change but I don't know in which way. if it does not change then I thing this woud be incorrect. I'm no expert but these are just ideas. Bob >OK so the clutch sounds like it is working. I dont know where the pressure >switch is on your car.

Just trying to work out what order the system goes in. As everybody else says, find a decent air con man...

If its not check that the pressostat (which is a switch in the gas line close to the front radiator with 4 leads on it) has battery volts on both pin1 and pin2 of connector. I think this makes contact at normal gas pressure but opens up if pressure gets too high. But then again it might be somewhere else......... T > Hi > [quoted text clipped - 11 lines] > TIA > Oli Hi OK I think I found the problem. The air con pipes are really cold when the system is running right until they go through the bulkhead. Obviously I cannot see what is happening through the bulkhead. In a fit of rage I punched the dash board, near the "sun sensor" thing in the middle. Low and behold, the air conditioning came on and freezing cold air came out the vents. My question is - in hitting the dashboard what did I move behind there to activate the system? Furthermore, how do I get to it properly so I can fix permanently? TIA Oli! Oli wrote in message ... >> Hi >> [quoted text clipped - 27 lines] >TIA >Oli! Sounds like the mixer flap was stuck. Get ready for the dreaded clicking drive motor noise as regularly discussed in this group. Visit the google group archive for the full details. Bob >Hi > [quoted text clipped - 11 lines] >TIA >Oli are both of your fans working? likely not.... the relay switches are right behind the grille upperside between the fans, triangularish box, check the bottom one, it likely to have its mass wire rotten of.... as the whole damn thing isn't in the right place first, and it is bad engineered. cheers Marc
