Picked up an 08 touring last week with no heat, bad windshield, bad 12v, and no red triangle or check engine light but stored P0A80 code. 175k miles. 1.)Got the 12v replaced and added a ton of coolant to get it all topped off over a gallon. This showed me the radiator had a big leak at the top. 2.)Replaced the radiator. Did not fully drain the block/trans axle just out of through lower rad hose. 3.)With the front end up on ramps, bleeder valve on top of radiator open and inverter bleeder valve open I added coolant until coolant came out the bleeder valves with no air bubbes. 4.) Closed the bleeder valves and with a large funnel in the radiator fill and full of coolant I jumped the relay to run the coolant pump in 5second intervals until I heard consistent liquid movement. This took a little more coolant from my funnel but not much. 5.) At this point ive gotten just shy of 1.5 gallons in (remember I didn't completely drain the system up front). 6.) Start the car up in maintenance mode 7.) Set heat temp to high and clicked defrost button 8.) After letting the car run like this up on ramps for 15 min I still had no heat and no more coolant pulled in via the funnel and no bubbles coming up. 9.) Scan tool showed coolant around 190 10.) Moved heat position to face vents and let run another 30 min. Still no heat. 11.) Shut it down and let it sit for about 30 min. 12.) Cracked bleeder valve again with small hose on it. No air just coolant. 13.) Fired back up still in maintenance mode let run with rad cap on. Coolant up to 190 again. Zero heat. The vent temp was equal to outside temp about 35degrees. I noticed that even in defrost mode all face vents still have solid air flow coming out. Switch to feet only and all face vents still have solid airflow but feet air is now blowing. Should I be looking at something other than an air in coolant system issue? Thank you for your help!!
