I got a 2005 Tahoe and never did LED conversion before, but went off the instructions I found or got with them. Everything lit up and had no hyper flash in the rear or the front and then one day went to use cruise and it was out. Did some troubleshooting today and even with the load resistors...

Cruise Control Not Working With LED Brake Light With Load Resitors I put some LED lights in my 2005 Tahoe and with the rear LED lights I did put in load resistors and lost my cruise control. Did some diagnosing and found out at the fuse block where the brake light stop fuse is I only had...

Rear Blowing Hot Air With AC On I have to ask this first due to I know my 2005 Tahoe has 4 of the blend actuators and have changed a few of them due to failure and it has been a while since I did change them to get it all working perfect again. I would say the Dealer is 100% correct on this one...

Does anyone know how the rear brake line should run up above the spare tire under the Tahoe? Walking back to the Tahoe I noticed that the brake line was hanging underneath the spare tire and know it should not be that way. I tucked it up above the spare tire for now to be safe so nothing on the...

This only happens in cold weather and has been going on the past couple years when starting it up the belt starts to make this squealing noise and goes away when the engine gets all warmed up in my 2005 Tahoe LT. During the summer it does not have any squeal noise at all and just noticed when I...

Go on eBay and they have some used ones for under $100.00 shipped. Their is a brand new one for over $300.00. Main thing is check their return policy and if they do not list one contact the seller about it. Plus, remember it is used you are getting so you just want to make sure it is good...

Was it in an accident? Because if it was the airbag control module needs to be reset in order to be used again. From my understanding they can reset your original and once repaired it will not need to be coded to your vehicle VIN due to it came out of your vehicle. I do know the p/n's of...

I keep reading through posts and keep seeing problems with the heat and the AC. Here is the problems.... They can blow warm or cold air on the driver and passenger side, get stuck, turn the key on and off and it will work.. Weird I know.... That is until they go out 100%..... Make sure you get...

Did you change the rear blend actuator? They have 4 of them and they all look alike being identical, but they are all different. I have changed tons of these and they are a total problem. Start out by hearing a click and then the problems begin. The rear is located under the right side under...

I know this is super old, but bad ground wires to the frames can make things work, not work, things go off, turn back on, complete havoc. I have a 2005 Tahoe and I have 3 of them and I know one is under the driver side door to the frame. One is under the front that comes right off the...

I know if you go really big or even bigger then you need to get I think it is a gear or something changed out for your speedometer. It is set for the revolutions that are stock... Can't recall exactly what they call it, but your speedometer will not be accurate if you go with bigger wheels...

I wanted to let everyone know on here that when you are experiencing multiple problems on your older vehicles and or/newer like dash lights coming on, things turning themselves on or off, and basically anything weird happening with your older vehicle. I fix many things myself, but I do have...

Here is something to check... Check your ground wires... I know sounds stupid, but they can cause so many things to go weird, not work, lights come on, etc. I have heard of mechanics over looking this all the time. I have a 2005 Tahoe and I have 3 of them and one started to lose its ground...

I see this is old post and see that you pulled it out and cleaned out the grease, but did not change it. Which one did you pull out? Plus, it should have some grease in it. Their are 3 in the front total, but one is for the fan. Their is another located under the console and a little hard to...

Did you ever hook up a scan tool and pull any codes? I know hard to diagnose on here, but are you aware of what a EVAP Canister does? Because what it does if the purge leak valve is stuck open it will cause a lot of the problems you are having. Do you have rough idling too? Here is what...

I think you are on the right track with the blend actuator. I have a 2005 and their are 3 of them in the front and one in the rear under the right side cargo compartment under the rear side glass with me having that tri-cooling or whatever they called it. I have an LT with the digital display...

Not knocking the Dealers, but they are always suspect due to they want to do everything from A to Z and not what really just needs it. I had a similar problem with mine in the rear and in the front too. Hard to type, but is it ever intermittent? Where like you get non-stop cold air, but if you...
