Issue 1: I followed instructions on this forum (very helpful) to remove and clean my EGR tube. I pute every thing back and the light is still on. what could be causing the light to still stay on? Did I have to reset anything? the code was P0400 which prompted me to clean to EGR tube.

issue 2: Driver winow dos not want to go down. I had followed instructions on this forum when it went doen 2 years and did not want to roll back up. there is a clicking sound when I push on botton...Any suggestions as to how to fix?

I really appreciate any help especially with Issue number one. I also have pics of the whole removal and cleaning of EGR tube. will post later.

EGR tube was actually almost completely clogged up. I will take to Autozone to clear the codes and see if that fixes the problem.

is it possible that the window issue could be the Copper springs below the window switches? two years ago I had to open the center console and fix the window problem i was having then, wondering if I should do that before trying to get a new Regulator....

all advice is appreciated, thanks 43 sqd
Thanks 43sqd, I disconnected the negative battery and I am waiting to see if the light comes back on.

Is the Regualator something I can fix or change myself...any instruction available here?

Here are some picture I took...
