i have 134A in my car and when i first turn on the AC the center vent temp drops to about 40F, which i like, but after about 10 minutes it goes up to 55 or 60 and only occasionally drops back to 40.
just wondering if it's low on refrig, or what?
any ideas?
thanks

As asked for in the troubleshooting guidelines post at the top of this page, give us high and low side pressure, vent temp and ambient temps so we can help you figure it out. Knowing the make and model of the speicific car you are working on would also be helpful.

Good luck,

i fixed it and the mysterious fan speed problem too...
