I turn on A/C I have no problem but it's pouring heat. Behind the driver side it's hot it
feels like it is coming out the side panel. In which it is. Can you please behind the driver side?

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.
