AOAguys this is haroon and i want to discuss a matter regarding my car a.c.actually as mentioned above i got cultus 2006 brand new back in 2006.now its been four years i have been driving this car with extreme care and love.currently its odo is showing 49k.as this summer starts i switched on the a,c and found that the a.c cooling was not upto to the optimum level.so went to punjab car a.c and got checked my car and they said there is a little difference and u should not go for its services.i kept on frocing them to get the unit service but they didnt.the reason for forcing was that i faced the same less cooling issue last summer too.got the gas level cheked last year too and it was upto the max level.so again after waiting for few days(this year) i took the courage and got the a.c serviced from my own mechanic.he opened the unit and found that the gas was full of oil and there was oil in the cooling coil.so he serviced the unit and pour the original genetron 134 gas.the cooling was still not upto the optimum level as it was when i bought it.now its been a month i have been driving the car on a.c and i found that after servicing the car was still not cooling well.i went to another mechanic, he also said that everythign is ok.but with the passage of time the cooling started to maintain the optimum level where it should be and i was satisfied with the performance .the main problem im facing is that MY CAR NOT COOLING WHEN ITS STANDSTILL.plus i got the gas level cheked and the mechanic said its ok secondly i want to know how these mechanics check the level of gas.when i see the filter bottle of my car i see gas moving and after few seconds it becomes clear but there are few bubbles moving around the glass of bottle.is it ok?pls help me in solving this problem.
one more thing and that is the compressor is in best state too.in noon it was showing the head pressure of 30psi and the mechanic said that its 100% perfect.so really need ur help in solving this issue as im fed up with this problem
Its Normal,while the car is moving the air flow causes the air used by tha AC, to cool where as when the car is still then due to no air coming from the front causes a performance lapse in the AC cooling,and being a 1000cc the AC may not be that much efficent.as you mentioned that you got it checked by 2 different mechanics and they said your setup to be ok so I think its better to use it instead of getting it opened again and again for services.
@daniyalthanks for the quick reply buddie.i know that when the car is at stand still it will be cooling less.i can still remeber those days when i got my car from showroom and i used to switch on the a.c for couple minutes while the car was parked.there is a fan on the condenser which also provide air to the condenser.so the a.c atleast work to some extent na!plus im not comparing the a.c performance of 1000cc car with 1300cc car.i kow the a.c of 1300cc car is far apart from this 1000cc cultus.secondly i dont believe in getting my car touched with a lallo panjo mechanics i know wht i mean.so opening the whole unit is not possible.i just wanted to know the optimum level of gas and how it is being checked.,thanks once again for ur kind and speedy reply
HmmmI have a suggestion,the fan which cools down the radiator is automatic and turns on automatically when the temperature reaches a certain temperatureif you know any good electritian you can ask him that what will be results if you get your fan connected with your ACi-e as soon you turn on the AC the fan will also turn on and when you are not using AC then it can be controlled by the thermostat.
they have pressur guage to moniter gas pressure one more thing check ur car heater system as if heater valve if the valve is leak the hot raidotor water come in and it effect the ac cooling
have u changed ur car expansion valve n dryer may be they are chocked and not perfroming at there best
@asad1heater pipes are also closed means no hot air in the dash@daniyalno bro heating is not the issue.my car never gets heat up.plus making the fan direct wont help me out as there are two fans.one for condensor and the other for radiator.so making the radiator fan is gona help
^^^^ YesI just completely forgotthis could be an issue aswell
does ur car Ac trip frequently ?or it keeps on
@asad1yes it does trip when the cooling is at optimum level.the orignal bello(thermostat kit) is there and its working perfectly fine.actually i myself have great interest in cars and whenever i get my car repaired i used to keep on asking the mechanic about different things and regarding his work.so regarding these small things in quite aware off.
You said car cools fine when its moving so there can be two problems.
the condensor fan is weak,Make sure its spinning at max rpm, fix a relay to it for max input..
The compressor is weak so its not working at idle.
@vaqasthanks for ur kind reply.ur first point seems impressive but let me add one more thing.today i tested my car a.c on standstill.actually wht happened is that i went to pick my bro from wahdat road and switched off the car upon reaching the destination.the car was parked under sunlight.i came after 10 min start the car and a.c to check the performance.the a.c was throwing less cooler air and the car was stand still.keeping the other aspects like hot weather,direct sunlight and etc wht u guys think at wht level the cooling should be.although i was sweating but not that much.plus there was a huge traffic jam so the car was again parked on the signal for like 5 mins and the a.c was on.i again tested the car a.c at night and it was upto my expectation but its not cooling that good in the noon?i know its because of temperature.i might be getting little touchy here........that could be the only problemor i thnk im expecting too much from this small car.i really think that this is the problem
@harooni agree with your last post bro. i own a cultus and its also 2006. i care my car alot too. so i guess we both are the same in this matter. cultus or any other small car doesn't cool sooner if you park it in direct sunlight. my advice is try to park in it shade whenever possible or atleast use sunshade. the one that reflect sunlight. use black curtain. these things will definitly help to improve its cooling. you have get it serviced thats all u can do. one more thing bro 1 this years its hotter than before
@angelnice to see ur post.i like those people who take good care of their carbro im always using black curtains and sunshade too.yes the sunshade does prevents ur dashboard from getting heated up and gives more cooling.it means that my car is not having any problem.problem is with me coz i own a 2008 xli too and the cooling of this car is awsome.so i thnk im expecting much more than this car.
