I just bought an used 2007 Suburban for my wife and on one foggy morning I tried the fog lights and they didn't work. I looked in the user manual for a fuse and saw one listing for the fog lights. It was in the fuse box under the engine hood. It is a 4 prong fuse (or relay) and I cannot tell if this is the problem. Can I test continuity across the 4 prongs or just get a new one if this is most likely the problem? Any help would be appreciated greatly.

alothough i know this sounds too simple and dumb.. ive seen yukons and trucks at my dealership with this same problem.. and it turns out the bulbs are blown or damaged.. so if u get a chance.. check out the bulbs.

cause some people tend to over think things... if youve got one out.. instantly u think bulb.. but if 2 dont work.. some people skip right over the bulb theroy and jump straight to wiring and relays.

Well the easiest place to start was the fuse box. It did seem really out of the ordinary that both fog lamps were not working. My next question, and I am sure all of you will find this funny also, but I do not know how to remove the fog lamp bulbs.

Sorry to ask again but does the whole fog lamp come out from the front or do I have to remove the fender well cover to get to just the bulb.

I finally squeezed myself underneath the suburban and found both fog lights unplugged. Keep It Simple Stupid. It was tough to get my hands into that tight area and figure which way they plugged in, but they both worked after that. I really appreciate all of the help.

      Some Assembly is Required

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.

      No Software Updates - Old Build

      By TrueBlue · Posted

      That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
