rear ac will not come on can someone tell me if they have had this problem and what the fix might be

I think I have the same problem! I charged the system again and The air got colder but I tried to turn the rear air on and got nothing no fan nada. I guess we could both use some help. I see there are some compressors and evaporators on ebay for about $200 Maybe this will do the fix.
Help it's gettin HOT!

Ihave already done that so i think it is electrical.by the way it was 102 yesterday suppose to push 104 today

Please post year, model and engine size. When you say the rear A/C won't come on do you mean the fan won't blow??
