PAUL FROM SPRINGFIELD, Mass: I own a 2006 Silverado crew cab Z71. The reverse lights, the dome lights and door chimes don’t work. I have checked all the fuses and can’t find the source of the problem. Any suggestions?
TOM: The reverse light circuit is not related to the courtesy lights or door chime. The door chime and courtesy lights may be related. I checked the wiring diagrams and found that the reverse lights operate through the run/start circuit and are routed through the ECM (Engine Control Module). The dome light is routed through the BCM (Body Control Module) and the door chime is routed through the run/start circuit and BCM as well. These circuits will have to be traced out to determine the location of the problem. They may share a common ground connection, and it it’s loose, this could affect all three at the same time. Only an in-depth diagnostic and tracing of each individual circuit will reveal the culprit. I saw no TSBs concerning this problem. Success to you.
WILEY FROM COLORADO: My ‘89 Honda Prelude 2.0 4cyl, 5 speed sat undriven for an entire year. I replaced the fuel filters, distributor, plugs, oil, etc. The car starts fine. However, once it is hot and I restart it, the car idles and stalls. I don’t think the problem is with the fuel pump, but I don’t know what it could be. Any ideas?
TOM: The best place to start is to determine what’s missing when the car doesn’t start. A vehicle has to have fuel, spark, and air (compression) in order to start. Diagnosis your problem might require that you do the following: (1) Install a fuel pressure gage on the fuel system to determine the fuel pressure (2) Use a spark measurement tool to determine how hot a spark you have (3) Do a compression test to “see” the internal condition of the engine. Only after running these tests can you proceed with a repair intelligently. Any other approach is employing the Wiley E Coyote philosophy of car repair which is: Ready – Shoot – Aim!
