This post is going to go back a bit.
A few months ago (back during Thanksgiving) I took my 2012 Ford Fusion in because I noticed my car was leaking a lot of coolant, as well as making a “waterfall” sound when I started the engine. I went to get it checked at a service center (non Ford) and was told the Water Pump was bad. I got that replaced, and my coolant had stopped leaking, and within a few days, the waterfall noise had stopped.
A few months later (now in January) and I had started to notice that my temperature gauge was starting to act funny. Whenever I would start the car, the car would heat up fine, and whenever I was driving (especially on the freeway) the temp would stay within normal range. However, once I got off the freeway, the temp gauge would drop slightly, and my heat would begin to decline from the vents.
I just got this checked out today, and was told the heater core was partially blocked, and the thermostat needed to be changed. Awesome… so I authorized this, and got my car back.
I was warned that since they were going to be messing with the cooling system, I would hear the “waterfall” noise again, but it would go away. That I do. But, I noticed my heating is even WORSE now then before I took it in. I am barely getting any heat from the vents, even when I am driving, and when I am at a standstill, the vents will be almost ice cold.
I am unsure what is going on… could it be the air in the system that is blocking the heat, or something else?
Thank you for your help!
