I have a 1990 buick century that runs great... until the engine or something heats up and then the engine just stops running, the check engine light comes on as it quits, i've changed the ignition module and 1 of the coils, i'm not a mechanic but am not afraid to try to fix this. I also hooked up an inline spark tester and when the engine has had time to sit I get good spark but after it dies there's nothing, any help you could provide would be greatly appreciated, thanks,
gerry

My left blinker does not work or left brake light. My blinker on the right does not blink when on. I was told that I may need to replace the flasher switch and may have some ele problems on the left. Power window on the driver side will not come down and the main control does not work the windows. I have to open my door on the drivers side to close the window in the back seat behind the driver. Can I get some help here. If it is easy I can work on my car to fix the easy things and from there I need to see where to go.

my 2000 buick does the same thing with the transmission, but I've noticed that my engine temp. runs hotter than normal just before it starts shifting rough...if I turn my a/c on it will drop the engine temp and the transmission quits shifting rough. I'd like to find the problem with it too..is it the engine coolent getting hotter than normal causing the transmission to shift hard, or is it the transmission heating up and causing the engine to run hotter?.. Guessing,.. I would believe it's the engine coolent temp not cooling the transmission oil properly.. causing the proble... IF so.. why is my engine coolent running hotter than morm?

My 2000 century low coolent light came on about a year ago, I checked the radiator and it was full, yes. . muddy looking stuff on the cap also. I immediately thought of stop leak too..then thought someone had mixed the green with the new coolent...so I flushed the coolent system myself..I've done mechanical work for over 30 years on my own vehicles...everything from changing plugs to rebuilding engines and transmissions. ..so I know I flushed it properly..which included bleeding the air from the system after refilling with coolent. Anyway.. after that my engine began runnning a little hotter than normal. I kept an eye on it and noticed it never went above 1/2 way on the gauge. But, this summer, the transmission began shifting rough..but only when the gauge reached 1/2.. and when it cooled down.. it would quit shifting rough. I found that when I turn the a/c on..it would lower the coolent temp to normal agin. So, I can't figgure out what's causing the engine to heat up some and the transmission to shift rough when it does. Some brown stuff showed up again in the radiator again, but it only accumliated on the cap. I'm puzzled.. is the transmission getting hot making the coolent run hot or is the engine heating up causing the coolent to get hot??? Any Reply will be appreciated!
