My brake and battery light stays on also the cat light and sometimes it doesn't want to start

my antifreeze will not hold...it is either leaking really bad somewhere or it is evaporating quickly.. got really hot yesterday have not driven it yet... needs more antifreeze.. also brake lights dont work.. i checked bulbs they are fine.. the center brake light works but the the left and right brake lights do not work.

when accelerating, move foot of gas, and the vehicle will switch lanes, checked tie rods,ball joints,frame mounts,motor mounts, dont know where to go from here

Where is the OBD connector location on the 90 and 93 V8Q? Are there any special connectors required to hook up to the OBD? I have a OBDII reader but want to check the codes on my 4 V8 Q's I own..... ug,,,ya ya, I know 1 of these is plenty of a headache for anyone.



this problem happened, then cured itself, and a few months later came back. When you flip to dims, the headlights go out and if the fog lights are on, they also do not light up. All other lights are normal. Flip back to brights, and the headlights come on bright, and the fog lights are not on (normal), but again, flip to dims with the fog lights on OR off, and the dim lights do not light up and the fog lights do not light up. There appears to be a relay or something in the schematic that coordinates the headlights with the fog lights, and wonder if that could be bad, and where that is located.
