trailblazin

i have a 2003 trailblazer, i went to the dealer for and oil and lube, they changed fliuds and told me that the license plates lights were out. so on the way home i bought a coulple bulbs... few days later i put them in, when i did, the rear hatch started trying to lock by constanlty clicking, so i closed the hatch and everything seemed fine,till i opened the hatch and it immediatly started trying to lock again, then driving down the road all the warning lights on the dashboard came on and the gauges fell(no oil presuure no water temp), the truck was still running fine( rpm gauge continued to work as well speedometer) but the electric doors and windows would not work, then after a couple of miles , approx. 2-3, everything went back to normal..
i stopped at a friends house and put it on a scanner it came back. 0 codes
but then listed all kinds of things like 02 heater, 02 sensor, cant not remember all the listings but it was not giving a good reading. do you know of any electrical probelms in the 03 trailblazers? so i can know which way to go to get this fixed. joco65@hotmail.com
