Normal A/C Temperatures?

When I had a new system put in about 3-4 yrs. ago, the temps at the vents on my older truck would get down to mid 40s if it was around low 80s outside. Then it would shoot up to low 50s if I was idling or stuck in traffic. Of course these numbers are a little higher when temps were around 90s or higher. I think I was looking at high 40s on a 90deg day or something like that.
Sometimes I wish I had an electric fan instead of the clutch fan. I might get a better performance when stuck in traffic with minimal airflow through the grill.....
Not to get off topic, but my a/c guy told me that because my fan motor was unusually strong in the high position, the vent temps were actually colder in setting 3 rather than 4(high).

According to the Haynes manuel, 1999 to 2006 trucks should be blowing 40 - 50 degree air out the vents. If the outside temp is very high the vents should blow air 30 - 40 degrees cooler than the ambient temp.

That sounds correct Randy777, I checked my '04 w/manual ac (after inquiring on this web) when it was new. Temps were supposed to be 40-50 w/**** on coldest temp & blower on "1". The temps then were just under 50. I'm going to check it again, with themometer this year. It never has been real cold, & it seems like most manual systems were that way in '04. I was told that the newer refrigerant is not as cold as before. I guess as long as it's in this temp range, no need for any service?

When it first came out the 134 was not as cold as the R12. But I believe that has changed as I believe the 134 is now under higher pressure. Problem is when in city traffic you don't get a great air flow through condenser and the air is not as cold as when driving on the freeway. An electric fan would help a lot. My daughters Corolla has one that comes own when you turn on the ac and it is very cold. If your aer is not as cold as it should be the 134 is not hard to add. All the auto stores have the cans and connectors
