Ac problems

Duplicolor · Postby **Duplicolor** » October 12th, 2007, 9:08 am

hey tuners, a friend of mine ac giving real problems, the car only cools when you are driving , if u only stop by a traffic light it gets hot. the compressor was changed 3 times, all seals where replaced and it was gassed, they tried and original b13 compressor and even a b14, and the same thing is happening and the guy wants to change another compressor, so im beginning to think..... from after the 1st 2 that the compressor, isnt the problem..

can one can give me some info on what to do ? almost 3000 was spent to fix the ac so far and everytime it comes back.. same thing..

did you try cleaning the condensor. road muck tends to fill the spaces between the fins and you loose the cooling ability. soak it with some soap water and then power wash it.

dont hold the pressure washer to close as that will bend the fins on the condensor

DE-VE,
well i dont know if the ac guy did that, but even if you change it it would happen over an over again??

^^ sounds like your referring to the compressor. the condensor is located in front of the radiator. it removes the heat from the gas. the radiator will have to be removed to change this.

try putting a piece of paper in front of the condensor with the fans running. it'll give you an idea of how powerfull the airflow through the condensor/rad is and try comparing this to a similar car. if the fins are plugged then you won't get good flow.

almost everything change it in an it still happening.

Postby **Dave** » October 12th, 2007, 12:13 pm

there is a pressure valve that acts as a fail safe when the air does not cool the condenser and thus shuts the compressor down
when this happened to me, my a/c wasn't triggering my fans but this is just a thought of the system to explore

yea check make sure that all the fans are working

Duplicolor · Postby **Duplicolor** » October 13th, 2007, 7:08 pm

alright guys id check it out tom.

Duplicolor · Postby **Duplicolor** » October 13th, 2007, 7:08 pm

oh yeah well i drive the car today for a while , but b4 the ac used to cool when was driving but now... it not even cooling for as getting cold..

Idle up unit how low does the idle drop wen he comes to a stop, and if it is a carburator engine from the b13 u need to check the hoses as well, also sounds like he needs a NEW A/C TECHNICIAN that a/c man must have your padner like he monthly salary at a fixed rate. Condenser well say that is changed so i assume he has a good one, but more soundin like an idle problem check valves as well....

Hope this helps

i had that problem recently . it was the condenser , a small leak in it . it wa s doint the same thing : when you ddriving its cold and standstill or traffic it getting hot . i end up changing the condenser and dryer and now the beyotch real cold . ice cold . if you want coolaire in movant REAL resonable to plenty ah dem others in the east/west corridor and they go check it out b4 you hadda spend anything

ronsin1 · Postby **ronsin1** » October 14th, 2007, 7:29 am

^^^ Always thought that coolaire was more expensive maybe I was wrong But I can atest that they do good work

debadlad · Postby **debadlad** » October 16th, 2007, 11:51 am

CBharath,
have a number for them?

Duplicolor · Postby **Duplicolor** » October 16th, 2007, 3:31 pm

when u change a compressor u have to change the drier ?

someone else check it and said the compressor not coming on.

oxidation · Postby **oxidation** » October 16th, 2007, 4:22 pm

i believe if the old system was using the R12 gas and a compressor that uses the R134 gas the old drier has to be replaced to work properly with the new gas

Duplicolor · Postby **Duplicolor** » October 18th, 2007, 8:01 am

oxidation,
ok thanks id find out

Postby **Dave** » October 18th, 2007, 8:07 am

u should always change the drier whenever doing ac work, remember it acts as a filter and use a new one please

the pressure valve is on the compressor

i was talking to an ac man the other day, he said when the coil in the compressor is breaking down, it would cool initially and then not work at all
they do rewind them but weight that cost against a used one

Duplicolor · Postby **Duplicolor** » October 18th, 2007, 8:17 am

Dave, when someone else check it they said the compressor wasnt coming on, cuz the car used to cool while driving and now....... it just not cooling at all
