It took me about two hours to find the problem!! I've checked all the fuses and relays related to the heating and air conditioning and found no problems.
I also looked at the wiring diagrams if there was any hidden relays or fuses and found nothing. Then I physically looked at the actuators of the: Blend door, Mode door and Recirculation door. They are all in working condition. But still it wasn't blowing hot from the vents.
So while I was under the dash looking at the actuators I decided to feel the hose going to the heater core that provides heat to the cabin.
The hose was not hot at all!! Funny, I was expecting to get burned.
I jumped out the car and looked at the engine bay and found the hose was bypassed from the heater core.
I think the owner did that because the heater core is leaking. I will find out soon enough when i reconnect it.
I'll be back!!
Got hoses connected to heater core and did a pressure test. Found out the heater core was leaking. Come to find out the customer just bought that van. Charged $600 to customer and had a new heater core installed.
It's been 2 years, what happened.
