Gregg,

I converted my '88 GL's refrigerant to 134a and get about 40-50ºF at
the vents depending on ambient.  Is the A/C compressor clutch engaging? 
Does your radiator fan come on as it should?  You may be low on 134a,
mine took 2 cans easily.

Subject: Proper AC temp?

Hey folks,
Just got my AC back in service recently in my 90 Westy (converted to
134a). I=
 know that cooling the interior of our vans was always a challenge, but
seem=
s like mine isn't where it should be.=20

With my laser temp gun pointed at the blower vents, I'm getting 70
degrees c=
oming out. Seems kinda high to me. Anyone know what the correct temp
SHOULD b=
e (keeping in mind this is now running 134a)?

Thanks,
Gregg
