I've had this truck for 3 years now and it's never had heat that works (front or rear). It's been a fixer upper. I'm trying to troubleshoot and be certain the front heater core needs replacing before pulling the trigger on the parts cannon. A/C works great. It ran hot in the beginning of summer due to a leaking radiator. When that happened, I had the radiator, radiator hoses, water pump, and thermostat replaced. Now it runs great again, just no heat still. I've had the system flushed several times (at least they said they did). I've flushed the rear myself and gotten a lot of debris from the rear core. I flushed the lines from the front to the back until they were clear. Just yesterday I replaced the rear core. I vacuum filled the system with coolant to hopefully get all or most of the air out. I verified that the rear blend doors work while I had that apart. For about 10 minutes the rear air started to warm up then got cold again. Someone suggested checking the heater control valve but I can't find it. It's supposed to be in the line right before the firewall but nope. The lines hook right to the core. This is where I'm getting stumped. It was suggested to me that it may be underneath at the rear but I haven't checked that yet. I have been searching the internet for info but there is very little on this subject and model.
So I told you all that to ask you this...is there a possibility the valve is underneath the vehicle? My mobility has been limited due to a knee replacement and I don't want to get down on the ground if I can avoid it. Also it has the electronic temp controls. Any help would be appreciated.
