2 Problems

New to the forum hope this is the right place to post. But I have 2 problems.

2000 GP GTP STOCK

First one is

When my heat/ac is on no matter what its set to, I always have like 75% of my output coming out of the defroster(dash) when its set not to be, is this caused by the digital unit itself? or is this something else? If i set it to full face I get a little more face, but its still like 75% on the defrost no matter what, crazy,

2nd, my TCS Light is on Off, and my ABS light is on , this is fairly new but its been happening for about 2 weeks now, Sometimes I'll start the car and it will be off then it will turn on and stay on and be on the next time I start the car etc etc.

Check Engine Light is on , but its for MASS AIR FLOW Sensor (needs replacing) and evap leak? which I was told is gas cap, which I need to swap as well.

Thanks!

As far as the ABS light is concerned, that has been a chronic problem on my car. I think there is a writeup in the writeups section on how to fix the abs light issue.
 
Problem 1 is due to your blend door actuator being bad. Change it out and it will fix your problem. There is a write up here too.

I've replaced mine. It's not fun due to you have to be upside down under your dash with little room. You'll definitely want to remove the front seat and lay a piece of carpet down.

There is a left hand and a right hand. I replaced the left and it fixed my problem.

Here's the writeup for replacement.

Evap Leak is from the Gas Cap not being tight enough. Make sure to tighten it good after fillups.
 
ABS Light and Trac control relates to the wheel hub. Make sure no wires are cut etc.. could be the hub itself too.
