OK this one has me slightly confused...I went to access my storage area via the rear window and found it to be locked. I "unlocked" it again from the remote without success. Long story short I am having intermittent problems where both rear passenger doors and the hatch/window are not unlocking...

I know I've seen it on here, but couldn't think of the right search phrase so here it goes. Finally got ride of the P0455 error but my fuel gauge reads approximately 1/8 of a tank lower than what is in there, would this fit into the instrument cluster recall that I have seen posted on here and...

Recently I have been getting an EVAP code (believe it is P0455), which I thought was resolved with changing out the fuel cap. Now I remain with an intermittent code and have noted that my fuel gauge reads accurate at startup and drops down to read 1/8th lower than actual. Any ideas if there is...

I was looking under the hood this am to just check it and noticed that I had a wire on top of my master cylinder. For the life of me I cannot find where the other end inserts. It is on the firewall and looking at the firewall from the front of the vehicle it is the second screw to the right of...

Is it possible for the engine to have a code and not trigger the service engine light. The reason I am asking is the other day mine came on and I had Autozone pull it and got two codes P0101 and P0455 (I think anyway it was for an EVAP leak). I know the P0101 has to do with the air volume...

A little help here...I have done a search but couldn't find what I was looking for. Basically I am looking to have a remote starter installed (right now do not see a need for a huge security system), but am concerned about having to carry multiple remotes (as right now I have the Tahoe and my...

I have pretty much reached a dead end with ideas. About three weeks ago my Tahoe threw a code P0101, it would intermittently go off and on for about a week. About two weeks ago it stayed on...I cleaned the MAF sensor and the code cleared for about two days. It then came back on, figuring the MAF...

Recently my driverside low beam light went out (Sylvania) and I am looking to replace it. I came across a new, at least to me, light bulb from Phillips it's called the Nightguide. Apparently it has different focal lengths to make night vision easier. Has anyone had any experience with these...

Hey all, I did the Big 3 wiring last Oct or November and since then have noted my voltage gauge at a minimum 14.4-15 volts depending on idle vs acceleration as well as a perceived smoother idle. However, this past week I happened to be checking my gauges when the idle seemed to be rougher than...

I know I posted this under the product review section...and later realized it probably shouldn't be there, so. I have had my Magnaflow now for about 2 months and recently I have been experiencing some intermittant backfiring. Doesn't seem to be related to a misfire, just an intermittant...

Hey all, I am planning on taking my Tahoe in for 50,000 maintenance ( I have roughly 48500 miles on it but will be doing some long distance driving this next month) and was wondering in addition to my planning on having the fluids (Trans, Diff, Oil, Brake) replace is there anything else I...

Hey all, I have a PCM tune (not dynoed but a tune none the less) and was wondering if: a) it were possible to use a programmer to adjust the tune settings? b) would there be any benefit to using the programmer on top of the PCM tune? 3) would would those benefits be? 4) any suggestions...

I am in process of replacing my O2 sensors and have run into a problem. I have been able to remove three of the four sensors and have remaning the post-cat sensor on the passenger side (just before the muffler), this sensor is apparently frozen in place and even though I have attempted to loosen...

Just wondering: a) How many O2 sensors are on our 03 Hoes? b) Where are they located? 3) How easy are they to replace?

Hey all, Maybe someone here can answer a little debate I am having with myself (and doesn't that sound like I have a mental condition :smilielol: ). But I had a PCM tune done by wait4meperformance which was basically done for economy at the 87/89 octane and the addition of a True Flow...

I have heard many things about using Sea Foam to clean out the fuel injectors but have been looking for a step by step for the 2003 Tahoe. Can anyone assist me in this matter?

Hey all, like all of us here I love my 03 Tahoe and the versatility it provides me and my family. I have no intentions on trading it in for a more fuel efficient vehicle that won't serve my family the way my hoe does. However I am trying to get the most out of it I can...So far I have switched...

Just a quick question...looking to do a pcm customization, does anyone know if it will void any warrenty I have with chevy?
