A/C Temps?


JRKRACE

Question

Does anyone know what GM considers "in spec" regarding the A/C temps. How many degrees? It seems my A/C is barely cold, yet the dealer says its within specs at 41 degrees. Is this true. Is there a way it can be checked with any tools I can buy? I really don't believe the dealer when my 95 pickup freezes me out of the cab.Thanks in advance..

I guess I can live with it at 41.......IF it really is 41 degrees. I have to check for myself because it really does not feel cold. Where I am it gets to be 90's with 80-90% humidity. Last Sept when I got the truck, it simply would not cool off. What is the easiest way to measure the vent temp's? Just a regular digital thermometer from Radio Shack or do I need an infrared point and shoot unit. I want to start recording some values w the ambient temps and get back to you guys. Thanks

a good digital thermometer would work better than a point and shoot IR for temp measurement in this case.

You are going from a (i take it by your sig.) from a regular cab to a crew cab. You are doubling the size of the cab. What do you want.

BTW are you putting it in recirc mode. 41 deg. is very good in a car or truck its not a refrigerator. :D

Well took it in to the dealer today and told them about the temps I took. Left truck there and went to New York for the day. Got the call on my cell.; TRUCK IS NORMAL. :cheers: Huh? :D I was told that A/C was blowing out 47 degrees in a shop that was 68 degrees. They said 20 degree cooling is normal and within specs. Went and got the truck back and measured temp myself. 47 Degrees. BUT the outside air was 51 degrees. " That's OK" I said to myself, I'll just take it in for the same problem another 2 times and then I'll Lemon Law the thing. It seems that's the only language they understand. I'd like to know if there are any tests that I can perform myself. I'm pretty good with a wrench....

Well, did a temp test today. With the ambient air outside measuring at 74 degrees, the truck with AC, recirc, and on position 3 could only muster 62 degrees out the vents. :thumbs: As I drove, the temp ROSE by 2 degrees. Looks like the dealer needs a new thermometer. Any comments?

The temp coming out of the vents is 41 degrees? That's barely cold? Man, what do you want, ice cubes? That is much, much colder than specs.

 

What's your ambient temp/humidity? There's a whole table of ambient vs. temp of air out the vent in our service information, but tables don't paste well, so if you tell me your outside temp and humidity, I'll post the appropriate spec.

 

However, if you think 41 is not cold, it doesn't sound like you're going to like the results. I will tell you that at 66-75°F (humidy less than 40%) MAXIMUM temp out of the left center vent should be 57°F. In reality, it is usually much colder than that, but that is the spec.

 

Here in South Florida, we'd kill for a vent temp of 41 degrees.

You definately have a problem. My 04 at 80deg outside yesterday froze me out and i have a 05 electric cooling fan and its no different than last year except the gas mileage.

You must be low or have air it the system. :cheers:

Yes he has a good one with temps like the old R12 days on R134a.
