My 97 3500b's air conditioner coil seems to be freezing. When I start out I get lots of cold air with a good airflow from the vents. over the course of a couple of hours, I get very little airflow and only slightly cool air. The pressure in the system according to a gauge on a refill canister is where it should be so I did not add any.
I think the rad inside of the heater compartment is getting clogged with ice. If I run the vent for a while and then switch back to AC I will get some more air but the whole cycle starts over. How can I fix this?
Thanks
Can you get access to the evaporator core, without having to disassemble the entire van? Might be worth taking a peek, and cleaning out any debris the inevitably collects there....
I will have a shop look at it I have a gauge that comes with the refill can it showed in the green so I didn't put any in.
I have no idea what the previous owner or her mechanic did so I think a professional is in order.
