Guys help naman po. kasi po yung air con nung crv (gen 2) pag naka idle lang or stuck po kayo sa traffic hilaw yung lamig pero pag inapakan niyo po yung gas pedal while on idle lalamig po yung aircon pero once you let go after a few min hilaw po ulit yung lamig....Ano po kaya ang problem nito

1) baka sa auxilary fan mo mahina na ang buga 2)pwedeng mahinang compresor and oil din 3)cleaning

have your system checked for proper pressure first.. have you replaced your expansion valve?? if not that could be the possible culprit.. also have your auxiliary fans checked

Your CRV are equipped with low pressure sensors to protect the compressor in the event of loss of freon like some other car.. At idle, there the pressure drops and senses it two low and shuts down the compressor like its supposed to do. As the rpms increase the pressure becomes normal and kicks in the compressor. On hot days the heat it effects the balance in the system without actually being there to evaluated it, the problem seems to be lack of freon. natural leakages occur over time especially if you never had the a/c checked. Have a mechanic check/ service it out and add freon.

i agree with with v6, and also dont forget the maintenance of your AC but make sure that the shop the would clean your ac system ( if ever ) dont use too much "sosa". may nakita kasi ako parang naluto yung evaporator.

Salamat po sa mga nag post! Ok na po yung air con so very cold

may leak sa evaporator and hose so I had it replaced surplus nga lang execept yung hose brand new. anyway ask ko lang if the price is correct

1500 evaporator surplus( 1month warranty)
1500 labor and materials (freon, hose, etc)
____________
3000 pesos totol

is this price correct or too much? thanks po ulit

bro, i think the price will justify at the end. kung hinid na babalik ang problem thus it will cool your head of the problem, then it's justified. sana lang pinalinis muna rrin yung blowers para isang trabaho & freon charging na lang.

Regarding the ones in bold above, that's not the likely cause. If the compressor has been disengaged due to low refrigerant pressure, increasing engine RPM will not cause the pressure to increase. The pressure will increase ONLY while the compressor is engaged.

When the OP stated that the A/C is only about half as effective while at idle proves that the compressor did not disengage. Though I agree that it's likely that the system is low on refrigerant.
