201 A/C doesn't work unless at highway speed
Not exactly breaking new ground here with the knowledge that the 201 has an undersized AC. Mine is a 1991 190E 2.6.
Bought the car 3 years ago. Never had any AC work or problems from the original owner. AC was adequate the first year, last summer was a little weaker, and this year it is much less effective. On hot days, I only get sufficient cooling when at consistent highway speeds, or at least going 40-50 mph with no stop and go. I don't have bubbles/clouding in the freon bubble window. I have all records and do not see where in its 13 years of operation that any freon has ever been added/topped off. To complicate matters, I do know that my auxiliary water pump (the one near the firewall at the back of the engine that circulates what into the heater core) is weak and needs eventual replacing. That does reduce my heater operation while at an extended stop. I don't suppose that should have any effect on my AC, though, should it. Questions:
