We just need to confirm what is happening. When you turn the A/C on it blows hot air? If this is the case that is either the A/C system is not operating or the blend door is malfunctioning.

Here are two guides to get us started:

Can you confirm the compressor is coming on? Also, let me know if I am not understanding the issue and we can go from there. Thanks

The A/C blows cold but it just gets hot in back of driver on the passenger panel. It's the only place it gets hot while A/C is on.

Okay. Do you have a separate rear A/C system? I am not showing an option for the rear system but I know these vans normally have one. If it does do you know if it was added later? If not then we have a possible weak system. So we need to check pressures of the system and go from there.
