If this is a r-12 car the bubbles mean you are low on freon. Now if it is a 134 car you cannot go by bubbles . It doesnt work that way with 134 , why I dont know but that was covered in Mercedes when they first introduced the first r134a car in the uS back in 92 or 93. Anyways what you need now is a wiring schematic of the system and a test light . If you need a diagram e-mail me your fax # and I will fax you one. The switch up top that is not turning on your fans is the 110 switch .It comes on when the car hits 110, it will come on high speed. What temperature does your car run ( hottest and coldest). I have seen the relays go bad but we need to test the switch and then relay. So, let us know.
