A/C

Post by broken »

As the A/C in my 1999 Daewoo Lanos se has never worked properly. I wont use it... (running some tests before I take it to a mechanic) so what I was wanting to know should the A/C Fan behind radiator come on whenever I turn on my A/C?

Yes it does.

From service manual
A/C ON
The ECM will turn the cooling fans on at low speed
when the A/C system is on. The ECM will change to
high speed when the coolant temperature reaches
97_C (207_F) or highside A/C pressure reaches
1 882 kPa (273 psi).

using the post for my A/C
but um.. that happened for me at first, i traced all the wires and such, before me and my brother found out that the "pressure switch" will even let the A/C turn on... added R-134a and worked like a charm, ran cool, not cold, cool air came out... but now.. there's no more refrigerant left... and there's no more cool air, Ive looked for obvious leaks and repaired them.. but before i rip almost the WHOLE A/C system out (pipes wise) is there a common spot or something that usually happens.. that has happened to others? or heard about.

my first leak was at the condenser if i remember correctly, the little cap looking thing next to the radiator.. any ideas?

(and for anyone reading, when filling A/C it is wise to fill on the LOW end, not HIGH end. yes there is a difference. idk exactly. the high end is right under ur nose, on the left, the low end is right under the intake pipe. usually has a black cap, as the high has a greenish cap. if i remember correctly, and when filling, turn the can upside down, so as the refrigerant goes into the line and not the gas, gas doesn't cool.)
thanks in advance

hm.... look on internet for the solution (google)

the system is the same as any other...

it is sealed system then no air should be leaving the AC system then it means that u might have a leak

what kind of noise did u hear? (more detail)

hahaha. some people live in mild warm/cool places.. i live in south cali.. +global warming= temps going up to +100*F
-.- so A/C will be a must this summer. period.
Jeff, my suggestion would be look at the compressor first, make sure if even 'clicks' on. if it doesnt, you got a problem. along with that here in the states, they have "EZ Leak" for A/C's which basically you put it into ur lines, and put on some cool glasses and see a fluorescent liquid where its leaking. my other suggestion.
like i said, my first problem was no refrigerant, and second was the little canister next to the radiators, was leaking alittle.. so i pulled it apart, lightly filed the surfaces to make it flat ish, then 600grit-ed the ends lightly, got new O-rings, then use a washer under the bolt to spread the the bolts surface area of tightening.

if you spot a leak, let me know, as i want to check mine at that spot too. thanks
