Picanto air con


Hello Sir:

not sure that I have a solution yet but I do have a few follow-up questions.

1. Is the airflow diminished from what would normally be expected? If so, open the Glove Box and remove the rubber stops on either side. Lower the Glove box so that access to the air inlet filter is gained. Remove the plastic securing clip and remove the air filter. Clean or replace as necessary. Also, run the fan with the filter removed. Does the airflow get better? Has the sucking sound disappeared?
2. Start and run the engine at idle; select the air condition fan on "low." engage the AC switch and note engine idle rpm: it should first drop momentarily and then increase. If the RPM does not drop, suspect the level of Freon in the system as below operational pressure limits. Most air condition systems shut down when the refrigerant pressure drops too low.

happy to answer any further questions and apologies for the delay.

Heard a belt break on my 1998 Hyundai Accent, but the engine didn't stop. What could it be?


you have torn an alternator, an air conditioning or power steering belt if equipped. check that the air conditioning works and gets cold if it used to and the power steering is not heavy if the car had it. if you broke an alternator belt your dash would be a christmas tree. if it had aircon and it doesnt work you need to look for your air con belt on the passenger side of the motor. if its not any of them something else has failed not applicable to any of them and it needs to be looked at asap.

Air conditioning stoppedworking. It has happened before but has always come back on. I don't know if it will this time


since you didn't say what stopped working, i'll assume you meant the cold air stopped coming. if this problem is intermittent, and that sometimes it works fine for as long as you need it, then start with the clutch on the compressor on the engine. those wires are small, and sometimes they break at the plug. if not that, the clutch could be giving you fits, either worn or bad. good luck.

Air con pump not engauging


Hi:

You should verify that your AC system still has a full charge of refridgerant, and if it does,
The problem is most likely the AC clutch assembly on the front of the compressor.

Since the dash light works, and the fan turns on, there is power to the system, but the compressor won't turn on if the pressure switch says the charge is low, and if you turn the switch, and someone can hear a click of the compressor clutch solenoid, but no air, the clutch assembly is probably the culprit

My blower only works on setting 123 + air con not that cold


You have a resistor array assembly going out. What you described is typical of the first resistor going out and over loading the second, which goes out and overloads the third. Replace the HVAC resistor array. Don't buy a used one. Spend the extra money on the new OEM dealer item. Good luck to you.

Overheating jeep & intermitant hot & cold air when heaters on ful


Hi, could be a blocked heater coil. Though I doubt it.

Some more info would be helpfull, but i'll try to give some help.

firstly, is the fan clutch working? it;ll look as though it is, and still spin the fan, but if you stand near the engine with the engine running and hood open and don't feel a force of air blowing out of the engine bay then the fan clutch could be weak. A way to test this is to very carefully and slowly try to stop the fan turning using a broom handle. if the fan clutch is working, then it;ll just kick the broom handle out of the way. you won't be able to stop it. If it isn't working, you'll be able to continue to place the broom handle and the fan will stop turning. as simple as that. If the fan clutch is faulty, you're engine will overheat. Especially at stop lights, parked with the engine running, and it'll kick out your coolant when you turn the engine off after it's hot.

secondly, if fan clutch ok, turn air con off and run engine. then turn air con on and see if the electric fan comes on immediately. With air con on, the electric fan should come on straight away. If not, the electric fan is faulty, and this could be a fuse, relay, or switch, or even the fan itself.

thirdly, if this is only occuring when you run at constant speed, and not at idle after a while, then there's a blockage in the coolant circulation. The radiator may need flushing, or the hose is getting kinked. Under vacuum, the hose can collapse and stop the circulation making the engine overheat as it gets hotter at high rev. sometimes, there are coils in the hoses to prevent this, and you may be missing one or two. These are usually at elbows where the hose connects to the engine, radiator.

Lastly, head gasket or crack in the head. check the spark plugs. If they look too clean, like they've been steamed clean, then you may have coolant leaking into the combustion chamber. At higher revs, this will cause heat and pressure buidup in the coolant system, eventually leading to overheating at speed. The crack/leak may only become more prevalent at higher revs, thus higher pressure. Even the slightest/smallest leak can cause this problem at speed but not at idle.

Good luck. Check the components first. Make sure the fans are working, then check the hoses for coils, and then the spark plugs. spark plugs should have a little carbon buildup. If it's the crack or gasket, then the plugs will look too clean. It may only be one plug/cylinder, so check them all.

Air Con cuts in and out and so does cooling fan


I have a 2008.5 Mazda 3 GS Sport and when you turn the air flow selector to windows or windows/floor, the air condition will turn on automatically. (Can't turn it off.)

Volvo v70 air con fault


This is probably a clutch problem on the compressor, either buy a new clutch or get a second hand compressor and swap the clutch over.
