Rear Heat Stuck On 2003 Express
Hi, I have a 2003 Chevy Express 1500 with rear ac/heat. It’s a conversion van with pro-air rear climate control. The rear climate control worked well until yesterday when it was stuck in heat mode. I noticed under the van is a coolant control valve (picture below). Is there a way to test this? Is there also a blend door? Thank you!

if that's a picture of your control valve then it's vacuum operated. Apply a vacuum and see if it opens. The vacuum is probably controlled by a another solenoid though and those usually burn out. As for your rear hvac it's might be aftermarket done by the conversion company.
