You said the evaporator is particularly cold, but no real cooling going on? I'd say the expansion valve is clogged. Wherever there's a too-large restriction, immediately downstream will be unnaturally cold. Could be the expansion valve, or even the receiver/drier.
I've had problems getting some systems fully charged, because the gauge set didn't fit right. If you're using R12, there shouldn't be any bubbles if it's fully charged. -- Jim _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
