hello steve
steve my 92 190e 2.6 A/C was converted to r134 the only thing
i change was the receiver drier as long as i'm driving the temp
gets as low as 43to41degrees but when i'm not moving the A/C
gets hot i have 2 new aux fans new fan clutch i didn't flush the system as it was empty i vacume it for 1hr any suggestion
as to get to satay cold at idle if i spray the avaporator with
water while at idle i get it to stay cold.thank jose in daytona beach.
