The front a/c doesnt blow cold air that great either but the rear a/c is almost warm especially when idle. Does it just need to get topped off with freeon? I was thinking of just buying the a/c pro.

 

Sounds like you are low on refrigerant but also could be several items. Do you have gauges to check the pressure, start there. Also, if you are Odessa, FL you might want to make sure you are not having a/c problems due to the love bugs jammed into the cooling system. Are you sure the cooling fan is engaging, these trucks in that year used an engine driven cooling fan with a electronic clutch, if it goes bad it won't pull air through the condenser and thus no cool air inside.

For what it's worth when I had the SAME issue on my 08 I was low on refrigerant, just a bit but our A/C tech at the shop vac'ed my system down and added about .25 lbs more than required. That really helped things and I was never complaining about cool air again.

 

I ended up adding the a/c pro. I added the whole thing. It feels somewhat better but i still feel like it could be better. Its just been really hot here lately yesterday it was 107

 

if it is worse at idle(therefore better when you are cruising), chances are you are not removing enough heat from the condenser. possibly could be cooling fan issue or your condenser is plugged. if you want you can try spraying cold water on the condenser with the vehicle running, if the vent temp drops, it is more than likely one or both of these two problems. FYI adding too much refrigerant can cause vent temp to be warmer.

 

How do i check for a plugged condensor?

 

By plugged I meant restricted. Spraying cold water on it helps to take the heat away. So if doing that lowers your vent temp, then the air flow through your condenser is probably restricted

These trucks have poor idle AC.

 

I have an '08 XLT with a similar issue. My front a/c works great, the rear only blows hot air. Additionally, I can control the rear air only from the dash panel, the rear controls do not seem to work.
