Brown-Out..??

My onboard options are inoperative. Power windows and rear defrost quit at the same time. Now my over head console(mpg, hwy gm display, trip odometer, etc)seems to work when I run through my options. However, my thermometer option quit reading the correct temp outside, in fact its way off. The other day I unhooked my neg terminal from battery to work on my heater core, ever since these options do not work anymore. I checked all my fuses in the passenger kick panel, they are all fine. Is there a relay somewhere or something that I need to check or what? Is it possible that I accidently fried these options?? How? Thanks in advance, Forum!

There are three circuit breakers in the PDC under the hood IF my mind serves me right. They feed voltage to some if not all of those devices, IIRC you can test them by pulling them and by pulling them out adding 12 volts to one side and see if the other tab has 12 volts, which proves continuity. Next look for power to one of the sockets for the CB. One side should have power IIRC.

Do you know what was good about the good old days? I wasn't good, And I wasn't old!

Senators and Congressman should wear uniforms like NASCAR drivers so we could identify their corporate sponsors....

After identifying which breakers control which option, Tested each one. All turned out to be working. This diagram helped. Turned out that my 'rear wash motor' fuse controlled not only my rear defrost, but also somehow my power windows. I believe it was a red 10amp. Replaced this fuse, now windows and rear defrost work again.

Check fuse #16 in that junction block also. 10AMP fuse

#16 works my overhead lights. funny, I don't have a fuse for that spot. took it out long ago because the family couldn't seem to close my doors all the way, kept running my battery down.
