Ac problem

1995 Dodge carvo van 3.9 v-6 134a

I replaced the engine and the compressor came with it. 88,000 miles. The clutch would not engage so I grounded it and added 2 cans of 11-2 freon to oil and the clutch would engage but the ac was lousy. I added another can and it was better. 10,000 miles later it's gone downhill.

It works decently at idle but when I'm on the highway it's almost useless. At idle the clutch is always engaged but on the highway it cuts in every 20 seconds.

It drips fine.

Any ideas?

Thanks!!!


Chuck

What the heck is 11-2 freon? Are you referring to R12 or some other unapproved substitute? The short cycling usually means low on refrigerant but the pressures have to be monitored before you can just randomly add more refrigerant. Your also forgetting the fact that you have a leak and will do some bad damage if you keep adding to it.

I mean it's the can of freon with 11 ounces of freon to 2 ounces of oil.

OH, OK, that's enough oil for now. It likely needs more refrigerant but be sure to monitor the gauges while adding to be aware of any blockage or other problems.

Why not fill it all the way with oil?
.Actually you may have too much oil in the system now it is possible to overcharge the amount of oil and have a/c not operate properly.

I doubt you caused any problem yet. Is that a single or dual system?
