I am having a problem with my LED panel lights (Shift position indicator and odometer). When my ignition switch is in the RUN position, the shift position indicator, odometer and radio stop working. When the key is turned back to the OFF position, they all work fine. When the key is turned back to the LOCK position and pulled out, the radio is still on. Also, the 10amp "Cruise Control Module and Switch, Body Control Module, Heated Seats" fuse keeps blowing out and the temperature gauge does not appear to be working. Is this an ignition switch problem or something worse? Are all of these problems related or is it more than one problem?

Replying to: steveo16 (Aug 04, 2009 2:51 pm) I have a basic schematic set on this vehicle, let me check it and get back with you. [edit] On the fuse issue, try turning off the cruise control switch on the stalk, and (considering it is 103 here today  ) don't turn on the heated seats. Put in a fuse and see if it pops immediately. If not, turn the switch to run and check fuse. See if the indicators in the instrument cluster come on. If still good, turn on the cruise switch. Try and isolate what function is drawing the high current. I don't have the complete schematic available, but I believe the functions in the instrument cluster that you listed as malfunctioning all come from the BCM, and the radio has aux power that (I believe) is also supplied by the BCM for the delayed power off function. The cruise control used to be a simple system, but I am thinking it also has a tie-in to the BCM. Try the tests I listed above and tell us what you get.

Replying to: steveo16 (Aug 04, 2009 2:51 pm) and oil pressure switch are wired so that when one goes it appears that they both go out. As far as the other problems I don't think they are related to temp guage.However, I've been wrong before. The other problems and possibly all the symptoms may be because of the ignition switch.Have you had it checked for trouble codes? I really don't know if I can be of any help at all. Check oil pressure switch and temp switch. Borrow a code scanner or take it to a repair shop to see what codes (if any) show up. GM did a lot of wiring changes to that body style between 1995 and 2004 because of electrical problems. Sorry I can't help.When you get it fixed,can you tell us what the problem(s) were? I'm curious.Thanks |

Replying to: steveo16 (Aug 05, 2009 2:23 pm) I would look first to the ignition switch. Were you able to determine what function was blowing the fuse?

Replying to: bigddetroit (Aug 11, 2009 4:11 pm) would not keep the pressure high enough to run right. It was only after I put in a factory fuel pump/gauge assembley that I got the right amount of pressure and the guage still works fine. I'm not saying that's whats wrong with yours but, that is what it took to fix mine. A GM mechanic friend of mine told me to put in the new GM pump and it would fix mine,and it did! You might think about checking your fuel pressure you should have 56 to 61lbs of pressure, I think I'd watch the mielage and guess on the amount of fuel left in the tank instead of buying another &300 pump. Again, it may not be the same problem I had but if it's not running exactly right and/or your fuel pressure is below specs it is worth looking into. Sorry I can't pinpoint an exact cause I hope this helps some. |

Replying to: steveo16 (Aug 13, 2009 6:37 pm) about your problem. I will let you know what he says. I tell you, I have never seen so much electrical problems on these Blazers and Jimmys in my life. GM has 43 technical service bullitens on them and several recalls. I'll be back... Thanks for your patience...
