i recently bought a 93 sc300 like 2 weeks ago

im in houston and its hot as hell here....

i was wondering if anyone has had the same problem and can help me figure out what it is.

when i first start my car in the morning or after its been sitting for a while the AC does not work, it takes like 10 mins with the ac on and driving before it starts to get cold.

and its only cool, not cold. ive noticed that it gets warmer when i come to a stop. if i drive on the freeway its really cold.

is it my compressor? i put in another can of 134a a couple days ago and its the same (its been converted)

im thinking of buying another compressor. its just odd that it works only after some time and some driving. i can start it turn on the AC and start driving on the freeway right away but its still hot for like 10 mins at least then cool down

 

Same thing happened on mine. It was actually ~2.5 lbs low. (or 2.3 lbs... I cant remember). The R134 conversion leaks. Period. (you cant get around this).

Drop another can into it or take it somewhere that they can monitor how much you put in it (dont overfill). That should fix it.

 

how come no ones SC's aC works
Everytime i read a for sale ad it always say they're ac doesn't work
lol WTF!

 

mine works

 

Take it to an A/C speciality shop... They can test and fix your leak and correctly fill the system.

 

damn i didnt mean to put this in the FI turbo engine section... i meant to put it in the normal sc3/4 section

oh well... i should pay more attention next time

 

check your dessicant and accumulator. If the refrigerant has some water in it, it will act just like you are saying

 

mine works
