any idea how to make the cars A/C better i mean cooler? please help
before 5 days the ac was working very good and suddenly yesterday it stopped working it was working 2-3 mins and not working 5-10min and then again working 2-3 mins.i took it to a garage near my house the guy said the compresor is the problem.today morning i took it to another service place in najma area the guy said there is no gas the compresor is ok.so i paid he put gas inside but its still not working good.its not cold.any ideas what to do? thanks
there wasnt circuit leaking.he put some soappy water and made pressure and waited 10 minutes.he told us if it goes down it means there is leaking.but the pressure meter stayed exactly same.
dene11, you have not mention brand name of ur car. basic idea of car AC's r same minor designe difference is there on each brand. Usally car compressor has lots of protection it does not fail suddenly until unless it has completed its life which is approx. 20000 hrs for japan made cars. It seems in ur case there might be some gas leak in circut.Make sure first that compressor is building enough(250 psi) pressure. Most of time mechanics also can not trouble shoot such problem properly and additional expenses come on owner head. PM me in evening i will guid u further if it is required since u r student so consultaion is free for u.
You should make
- a valve plate test
- a refrigerant charge test
- a leak compressor test
- a belt tension test
- a clutch air gap test
- a clutch voltage and current test
- a shaft turning test
- compressor oil check.
