The compressor is probably froze up.
why 2003 ford focus stall when air conditioner is turned on
Try replacing your Oxygen sensors they are located on the catalytic converter. I had the same problem with my 94 Caprice and that turned out to be the problem.
Primes the system when the fuel pump is turned on so the engine can start right after cranking. As soon as the fuel pump gets its voltage it gives a squirt
Throttle positioning sensor
Yes chevy caprice do run when battery is disconnected as long as the cars alternator is in working condition to keep the car goin once turned on.car won't turn on without battery just like any other.
its because the aircon uses up to 10% of the cars engine power. all cars with air conditioning have a change in revs when the air co is turned on or off. the larger the engine the less noticible the difference is. its because the aircon uses up to 10% of the cars engine power. all cars with air conditioning have a change in revs when the air co is turned on or off. the larger the engine the less noticible the difference is.
A bad thermostat can cause overheating in a Nissan Frontier when the air conditioning is turned on. A bad compressor can also cause this.
When air conditioning or front defroster are turned on it will turn on A/C compressor which requires the A/C condensor to be cooled (via radiator fan).
It is normal for a little vibration with the air conditioning on due to the compressor working , fans on , and engine running a little warmer. On at least 92-96 Toyota's the fans automatically come on when the ac is turned on
Blower fan relay is stuck or fused contacts, replace it
It is not supposed to be on when engine is running unless there is a problem.
Check your electrical system. You probably have a short circuit, melted switch, or ghost(and no I do not mean a creepy spooky ghost) in the system.
The extra load imposed by the air conditioning compressor is overheating the engine. This could be caused by numerous things, but the most common would be either a broken thermostat, low coolant, or a badly tuned engine. Take it to a mechanic.
The idle compensator speeds up the engine when the ac is turned on to compensate for the additional load on the engine. If the engine is surging when the ac is on and not any other time then the compensator is probably bad. If it surges all the time but gets worse when the ac is on then look for an intake vacuum leak.
What you are likely hearing is the electric fan that cools the radiator and Air Conditioning condenser. This is likely remaining on to remove excess heat from the engine coolant to prevent a boil over after shutting down. When the engine is shut down heat continues to be transferred into the coolant for a period of time. You should also notice that when the Air Conditioner is turned on in the car that the radiator cooling fan will remain on continuously. This is necessary to cool the heat exchanger(condenser coils) that remove heat from the freon in Air Conditioning system. When the Air Conditioning is not on the cooling fan will activate only when necessary, which is when the engine coolant rises above a temperature that is too hot to cool the engine.
The air conditioning uses up the battery power.
When a check engine light comes on, it means that there are issues with the engine. It gets turned off when the person resolves the problem that caused it to turn on.
It is probably your cooling fans. These are electric and may run with the engine turned off. It is probably your cooling fans. These are electric and may run with the engine turned off.
because of u <<not part of my answer>> Probably need to check/do an allignment.
first of all have you tried to have your car on and pressing the button. some of the older cars you have to have the car on or at least turned to where the dash lights turn on like the engine light for it to work
If the fan keeps running it's because it is electric and wired through a temperature switch not the ignition. Electric Fan running is independent of engine running. When the temperature is high enough to start the fan, it goes on. when the temp drops the fan goes off. Temp does not drop right away when the car is turned off. It can actually rise several degrees when the engine is turned off. The fan running after engine shut off is actually a good thing that may prevent radiator overflow
because someone probably turned the engine on
is this while the egnition is still turned on if so its probably just cooling the engine and should switch off after a minute Mine had an issue that continued for several minutes after removing the Key on my 2000 Volvo S40. It also impacted the air conditioning. The fix for me was to replace the temperature control sensor and the thermostat. Thermostat was only $7 or so, the temp control sensor was more like $45-$50. I did this, and was able to get my engine running again, but still had the air conditioning issue. turns out that one of the parts I had replaced was bad, I replaced both and everything worked great. Not a hard job to do yourself, should take 15 mins or less.
The key has to be turned to the "Run" position, but the engine should not be running. The key has to be on to power up the ECU.
