Hello. I have a 2003 SS that is having some electrical issues. When I start the car the heat, defrost (including rear) and blower does not work. What's unusual is it will start working after about 5 minutes or so of driving. Also, I noticed that my homelink system (direction,mpg, etc.)does not work either when this is happening. When the heat, defrost and homelink system does start working it will stay on until I stop the car. When I start the car up a few minutes later or a day after, the same issues come up where there is no heat, no defrost and the homelink system is not working. It will again start up after 5 minutes or more of driving.

Can anyone share some light on what possibly the problem is and how to fix it? Any input would be appreciated. Thanks.
