There seems to be an electrical problem with the window switch wiring. When I try to open the rear right passenger window from the driver switches, it doesnt work so i have to use the switch in the rear to open/close the window. After i use the rear switch the driver switch begins to work again. Anyone having this problem?

plus, the engine coolant (pink stuff) seems low. the plastic coolant holder isnt completely filled; should i fill it? if so, with what? (not the green stuff, right)

 

Did you recently disconnect your battery? If so, then you have to reset the windows to make sure the drivers controls can move all the windows. To reset the the windows you need to go to each windows own controls and roll the window to full down position and then full up position. Once you have done this at each door you should be able to use the drivers controls, it's in the manual. If you are referring to another issue then I'm sorry, can't help ya.
