any suggestions if ac throw warm air after couples kilometers drive at beginning its fine but after some kilometers its throw little warm air.please any suggestions guys.....
It can be small refrigerant leak , or Compressor clutch that wont last for long and give you warm air .You need to check that is it comes back to give cool air after warm or it just keep on giving warm air ?
The likely culprit is moisture in the system causing freezing at the expansion nozzle/valve.
This could also be the aftermath of removing thermostat valve
if i stop the car for a while then it comes back to cool air..otherwise it keeps throwing warm air Sir
