I have a 1998 Dodge caravan with 144000, latley when the ac is in max cool and i am driving on the highway the low side hose freezes up and the evap freezes also so the air coming out of the vents slows down. I turn it off or open the ouside vent and it will un thaw. My limited knowlwdge stells me it is low on charge but the AC place i go to says its ok. Yesterday the compressor belt broke so i replced it and the ac worked for a while and now it will not engage the clutch. i can not find the switch to jump to try to put some freon in it. any ideas?

if it is freezing up you have to much freon or your temp switch isnt working. also check your condensor for bugs/dirt.

If the evaporator and low-side hose freeze up, the system may be overcharged with refrigerant or the temperature switch may not be working. Also inspect the condenser for bugs and dirt.

Conversation Summary

The owner of a 1998 Dodge Caravan reported that on max cool at highway speeds the low-side hose and evaporator freeze, reducing airflow until the system is turned off or outside air is used. A shop said the charge was okay. After a broken compressor belt was replaced, the AC worked briefly and then the clutch would not engage. The expert said freeze-up can be caused by too much refrigerant or a faulty temperature switch and advised checking the condenser for bugs and dirt.
