Check Light

[jakethesnake110]

so my check light is on and my coolant light and windshield fluid light is on.. i realize that the check light is on bc those two are on.. but my coolant and windshield wiper fluid is full.. altho my temp guage kinda bounces from time to time.. most of the time is runs cool.. but other time it justs to half way.. but never much higher.. it doesnt do it all the time.. but kinda often.. more often than i would like it to.. i dont see any leaks and its holding coolant so im not sure wat the prob might be? any answers? thanks guys

Check coolant and washer sensors. To test simply remove the plugs going to the washer tank/coolant tank and jump the pins together with a paper clip and cycle the key. If the lights turn off your issue lies with the sensors.

As for the temp gauge, remove the cluster and tighten the grounding nut behind the gauge. The gas and temp gauges sometimes go wonky if the nut isn't tight.

If you are going to remove the cluster then you should check the SI board/batteries. I would not be surprise to see corrosion eating up your board.

Also the washer fluid sensor can rotate so it doesn't float properly in the reservoir - make sure it's upright.

so where exactly is the si board?/batteries? seems as if i may need to check these.. ive done research and it seems to be a common problem..

Si board and batteries are in the lower part of the cluster.
