Combines R62 NO CAB AC VOlUME OF AIR FlOW

[silver_tin_tank]

WE had same small air volume Made a inline fan and put it in the air line just after the A_c box, twice as mutch air Some boats have same type of thing to get rid of fumes in under water space all the best tin tank

Same complaint here. I installed an oscilating fan in the top right hand side of the cab. Got it at Wal-Mart for 10 bucks or so. Works great. Not enough air flow has been a complaint in these cabs from day 1. It should have been pretty simple to fix that at the factory.

We had the same problem in an R-62 6 years ago. Dealership discovered that the fan was installed backwards. It turned the correct way but the vaines were backwards. Our 2001 R-62 doesn't have alot of airflow either and the heat from the engine has burned wires on the compressor in 2 at least 3 times in the last 3 years.

this has been covered before but, check all corners of the air box for cracks at corners that were not welded, use non expanding foam to seal. Use a brush and air to clean AC core after removing heater core and cleaning it as well. IF you have a dirty core you have a leak between the filter and the fan, seal this as well. While you have the blower hsg down run a test wire from the relay in the cab to the pos wire on the blower and MAKE SURE the ground is good. Turn the blower on high then add in the direct wires, IF the fan picks up speed the fan switch is not delivering full amps and voltage on high. We have installed a relay (generic as in semi trucks or your AC relay as in l3's) which directly connects full bat voltage to fan motor when in high speed. Connect a wire to the cab relay to the added relay then to the motor, jump from the high wire to the relay to trigger it and of course you will have to run a ground wire to ground the relay magnent. The current fan switch pullls the motor as well as the AC comp clutch. Too much for the little three speed switch. The relay really works most cases (I left myself an out there notice - we have had noticeable increase in all cases - hope it works for you).
