Asked by Nov 13, 2012 at 08:45 PM about the 1998 Chevrolet Lumina 4 Dr LTZ Sedan

Question type: Maintenance & Repair

No power to starter soloind, fuses all good with power to theft deterrent module and VAT, I am down to testing starter relay, which is a 2x2x2 black relay, but can not find it. Not in driver side or passenger fuse boxes, not behind glove box, or behind radio, or on steering column. Does anyone know where this part ia actually located: maybe further behind dash board requiring that the dash be removed.

Thanks Tom, it is there, it is hard to find, it is up high on the left top of the glove box compartment, took awhile to find. The security light remains on for a few seconds then goes out as it normally does. It will not start in park or neutral, no power to solinoid. I checked power at all the fuses for anti theft module, theft deterrent relay, etc, I am pretty sure it is the relay itself. I will check it tomorrow. Thanks for your response. I made me look again.

Since this seems to be a common quesiton based on my on line search for an answer, allow me to elaborate, the starter relay, also known as the theft deterrent relay, is in the passenger side dash board, a few inches above and to the left of the glove box, and basically behind the passenger side air vent. You will need to remove the glove box and a air tube from the firewall to the vent. The relay is a 2 inch cube, with yellow incoming wires, purple out. Can test with voltmeter to see if power in comming in (ground to body) and ir circuit is completed by grounding to the outgoing purple wires (one goes to starter, tjhe other to the theft deterrent module (I think) which controls the ground. If it power goes to ground through purple wires then the problem is likely the relay, if not, find the theft deterrent module test it. You will need to lay on your back and look up under dash to see the starter/theft deterrent relay, Good luck,
