I just got my car running again after sitting for 7 months. When it got parked the AC worked great. So I have an 03 with duel climate, the compressor energises and spins without issue. I get kinda cold air on the pasnger side (for sure ACed but it should be colder) and straight vent air on the driver side. If I slide the sliders to hot then I get hot air so I think the climate control unit is working. Where should I check first? If the blend door was bad wouldn't it be blowing hot air all the time?
