2000 Venture van. A/C dont work.Need a good troubleshooting step?

Question

When switched to a/c the light indicator is on but no cold air is blowing. Its on the cold side and on return mode. I checked the a/c compressor and the clutch is not engaged. The fuse and relay is good. I recovered and vac the system and recharged with 3 pounds. still a/c will not work.

Answer 1

Have you used a jumper wire to bypass the wiring to engage the compresser and if so did your ac get cold?  your presser  switch may be bad and not let the compresser engage or your system may not be fully charged.
