Weak A/C
 

My 1977 450sl does not blow enough air through the vents. Is there any booster fan or a way to turn up the fan speed to help?

Is air coming out from the defrost winshield vents or the floor vents at the same time that is from the frontal vents? if so you have a stuck valve that is dividing your air between both. Good luck.:cool:

my 92' 300CE doesn't get icey cold...ugh
anyone know why or how to fix?

I checked the vents and the dash. They work properly. I just am not getting enough "umph" out of the vents. Texas heat rarely can be remedied, I was just hoping for some super duper turbo blasting fan that could re-freeze the icecaps. Maybe there is a rear unit that I could add to have a lower set of vents. Thanks for your suggestion.
