A/C not Running!!!!

Hey guys, I have a 2001 330i and am the only owner... up to now, my a/c was working fine, but all of a sudden it just stopped working. When I turn on the a/c nothing but hot air is blowing out. I used a can of R-134a with the dye and I saw it coming from the low end of the a/c valve. Any ideas on what might be causing this?

low end of the A/C valve?.... do you mean your low pressure port; or other valve?

anywayz, if you see the dye... it only menas you have a leak in your system, and the location where the dye exposes itself is where your leak is.

low end a/c valve... i will assume this is your low side port. you can try and change the Schrader valve... and then test for proper seal with soap suds ;-)

after all that is done, you'll still need to have your system vacuumed out (to eliminate air and moisture in ur system) before you reload R-134a.

You are right... it is the low pressure point. I will pick up the part this weekend. Any idea on how much it will cost to have the system vacuumed out? is it something simple? any special parts needed?


Thanks for the tip

schrader valve replacement +/- $3.00
schrader valve extractor/installer +/- $5.00

In California, average price for vacuum & recharge is $25.00-35.00
