BMW Repair: 92 325i A/C, r134, harness connector

Question
After work the other day I had trouble starting the car.  After letting it sit for 30 minutes, I was able to start it.  When driving home I noticed the A/C was not blowing cold air.  I had taken the car out earlier in the day and the A/C was fine. Any suggestions?

Answer
Checking the wire harness connector under the intake may be or have corroded terminals and could cause the hard starting.You should also check your fuel pressure to make sure it is correct.
As far as the a/c goes,check to make sure the system is fully charged.Being a '92 it is R12 unless you have converted your system to R134,which is easy to get.If it is low I would evacuate the sysem and change it to R134.The retrofit kits are available at your local parts store
