My 91' 190 is having an a/c problem it has been leaking freon and has to be charged every two weeks. My mech. thinks it is the evaporator but I have not done anything yet. Tonight I went to town and the a/c won't wor at all now. I turn it on and the compressor kicks in but no air comes out the vents. Help! and Thanks again!

Fix the leak. Are you using dye to locate the source of the leak? If not add dye to the system. This is the most reliable way to leak test the system. With a leak that is big enough to lose the charge in two weeks it should be very easy to find with dye.

Check the blower switch on the dash for no fan operation. Also Corky is right get it fixed. It has to be costing an arm and a leg to charge so often.
