Hey everyone,
I have a 2003 Tahoe 4x4 with the 5.3. I have an issue I am trying to figure out. So the other day I was heading out to make a car payment in my tahoe and on the highway my abs light popped on and my brake light popped on. Then the transmission started shifting irratically. Well...
I figured out my actuator issues i been having. I need to change the one by my gas pedal and the driver side actuator. I unhooked the one by my pedal and manually changed the heat from just the defrost vents to my dash vents so i figure i need to replace that one for sure. And the heat is luke...
Ok so after find its location which is by the gas pedal i assume this is the ricirc accuator. I was told to unplug it and on the side of it should be a gear type lever and if its on defrost it would be stuck at the top so i rotated it down and now i have heat coming out of the vents really well...
Went out and played with the rear controls it all engages and i can hear it change when i change settings. Now upfront it just stays the same weather i have it on defrost, floor or vents and the circulation i hear nothing and it dosent engage or do anything at all.
Well the rear blows cold. But the front is still hot. So i figured for the rear i might need to replace the rear blend door actuator. Havent really cycled the rear i just got the tahoe a few weeks ago but noticed the rear was blowing cold while the front wss hot but when i tried it then it...
So my heater decided the other day to start acting up. I am not getting good air flow from my front vents for heat. Now it is hot but i get very little out of the vents except the defrost vents on the dash works great. Ive tried every setting but still very little air flow out of the floor and...
So i measured it, it is 3. So i should be able to buy a 3 in and 3 out muffler for it and it should work? I am taking it to an exhaust shop as soon as i can get some quotes on some mufflers
More than likely i will tommorow after work. I didnt think about it while i finished pulling it off today. I was wore out from work and didnt even cross my mind.
Wanting to make sure i am right before i buy a new muffler. I just got 03 tahoe. And i think someone who isnt very smart tried stealing my muffler thinking it was a catalytic converter lol so they started to cut it and i guess when i thought i heard something i spooked them off and they ran when...
So thought id post an update. I got out and starting looking at wires and checking fuses. Checked under the hood and everything was good. Then i checked the pcm and tcm fuse in the panel on the dash and well first off the fuse was too big it was a 15 amp and not a 10 and it was blown and had a...
