I have a 2014 GMC Sierra 1500 5.3 2WD 4 door. Only cold air coming out the vents. So i pulled the glove boxes out so I could see the blend door actuator. I could see the clip wasn't connected to the actuator. So I connected to wire clip to ghe actuator, and was excited to see if maybe I had found my no heat issue. But, now my teuck won't crank. Turn the key, 1 click and nothing. Ive checked every fuse. All good. I even jumped the starter relay. The truck would turn over but wouldn't start. I'm clueless.
