My R75 has terrible air flow but my a/c guy said it is completely charged and working fine, just need to clean my condenser out. Never done that before and I know it is under the cab but how do I get to it and what is it the best way to clean it?

easy to clean out. Maybe it is your cab filters. There is one in the case under cab one in roof of cab above right side glass & one under console. If you have to clean the evaporator under cab take the screws out that hold on bottom of housing then you can lower down the evaporator & wash out with garden hose.

Be sure if it is an early 75 to tape off the long slit openings on both sides of the two front cab posts. This will increase air flow a lot and stop the moisture from collecting dirt on the windows at night. Blowing out the condenser works but where it is located under cab it is very easy and better to wash it out after you blow it, then blow all the water back out. I try to do this every couple years.
