I have a 1989 Nissan truck, 4 speed, 2.4 liter. It runs good but has developed a weak air conditioner. For a few weeks it was weeping or dripping a/c condensate water on the rubber mat on the passenger side on the floor inside. I looked several times to see if there was a quick fix but saw nothing. Today, the A/C went down to almost no cooling. It forced me to park it around in the sun (way over 100 degrees) and line up some sunlight into that area under the dash, to be able to see. I saw a rubber hose inside and below the dash had come loose, it was dripping water. I stuck the hose (end) back on and I could see that it was intended to drain or circulate that water into the fan area (to apparently cool the fan?). Anyway, now it runs and it cools a little. It makes no noise. The fan appears to work.
What probably "went out" on my truck a/c? Did I burn up the condenser? Or, would it recharge and be okay?
Another couple questions. This old truck is in real good shape and I'd like to keep this a/c as it is --not forcibly upgrade it to politically correct (bad) refrigerant. When I take it in for service, how do I avoid having them put in that new (bad) refrigerant? For instance, if they change the condenser, I want them to replace and recharge it with the old style refrigerant. Thanks anyone for ideas and suggestions.
