I'm many miles away from my service manual, and want to add some R134a refrigerant to my air conditioning system. Can someone verify which system port is the low pressure side?
I've located both ports - there's one at the front of the truck, just behind the condenser, and the second one is near the firewall, a short distance from the dryer/filter.
Both ports have the labeled covers (one L and one H), but I want to make sure a tech didn't swap the covers inadvertently on a previous service. I'd hate to blow up my cheap can of refrigerant.
Thanks for any help,
John
