Passlock Troubleshooting

[prostreethotrods]

i have a 2000 yukon xl, and lately, and only in the cold weather i run into a problem with a no start,,,,wait for 10-15 mins and then it restarts, drive it for 10-15 mins and then the security light comes on, but only in the winter , never in the summertime...

what can it be...ignition switch...sensor in the steering column housing, wiring leading to or away from the sensor, or other electronic issues...

also the gauge cluster, where the shift indicater and odometer,,seems to flicker,off and on,,cut out and come back,,i push in the trip odometer needle and it seems to correct itself.... but not at the same time as the other issue

thx roger

I have a 2002 Olds Alero that does the same thing. Dealer said that you need to replace the whole ignition switch and possibly the wiring behind it. There are a ton to complaints on this system. I think they quoted like 450 to replace the ignition.
