Hi all,
I have a strange issue with my 2008 Tahoe remote keyless entry system. After the truck sits for a few hours, the key fobs will not unlock the doors right away. I have to try a couple of times and then wait anywhere from 30 seconds to a couple of minutes before the fob will unlock the doors. I have done all the standard troubleshooting... different key fobs, disconnect the battery, check for battery drain, etc. with no luck. Today I decided to hook up a multi-meter to the battery and found that the amp draw from the battery jumps from .05 amps at rest to 1.5 amps when I hit the unlock button. So the truck is responding to the key fob but is failing to unlock the doors initially. I've also noticed that sometimes the climate control buttons will light up while I'm hitting the unlock button on the key fob waiting for it to finally work. I'm thinking it could be a faulty module but I'm not sure which one controls remote keyless entry. Is it the BCM or does it have its own module altogether? Any help is appreciated!
