This problem happens every now and then; I'll go to start up and none of the dash lights will come on but the car starts; after about half a minute of so the lights then come on but they are followed by three beeps and the service vehicle soon light comes on. At this point the light by the blower button is not on and the heater doesnt work. I also noticed that during these times if I am in park the day running headlight do not go out. After driving a couple of minutes the heater light comes on and the blower works fine on all settings.

Any feed back that I can get on this will be appreciated....

 

My guess would be the BCM is having fits. Could be just corrosion on the connectors since it seems to be intermittent... I don't know anything about how to clean those connections specifically, but hopefully this'll point you in the right direction..

 

Thanks for the response just the same; I'll begin looking at taking it out and eyeballing the connectors. I'll post the results when I get done.
