Heat Only Works During Acceleration
I've got a 2014 base, manual. I purchased the car about a year ago and before I purchased the car, I tested the heat and it was working. Now that it is colder out, I finally tried to use the heat and noticed that it wasn't working.
It doesn't matter which setting I have the air on, heat will never come out yet AC works perfectly fine. I noticed that whenever I accelerate hard, the heat does work but as soon as I am done accelerating the temp of the air coming out goes back to whatever temp it is without heat.
I did some research and figured it was my blend door motor causing the issue. I ordered a replacement motor and popped out the dash. I didn't notice any clicking like the gears were skipping so I took out every single blend door and tested each one- every single one is working fine. I don't have a left-side blend door, but I checked the right side, along with the foot air vent, re-circulate and defrost motors. I'm not really sure what to test next or what the issue might be.
