Guages in 85 s-10,don't work with lights on.What's the cause?

I bought an 85 s-10, and all gauges work, until the head lights are turned on. With the lights on all gauges, drop to the bottom. We changed the engine, and it runs fine. I tried to drive it at night, and all gauges stopped working. There are no dash lights visible. When the lights are switched off, gauges again work. Has me baffled, please help !

Electrical gremlins are wierd. My guess is there is a ground unconnected. There is the main ground from the battery to the motor and probably a pigtail ground the the body.

Did you mess with anything under the dash?

Truck is dead...all lights gauges work but turn key to start and nothing..


Is the truck dead...or do all the lights and guages work? If the lights and guages work then the truck is not dead.
First, make sure the truck is in park or neutral. If the truck is in either of the two gears and still does not start, check the crank fuse under the hood. Also check the immobilizer fuse (2amp) as well.

Guages don't work


That could be the cluster gauge assembly itself and it may have bad connections on its circuit board or the body control module that controls the cluster gauges has a problem.

My 1999 Acura 3.2TL is experiencing problems with the gauges. They sporadically go nuts. I've found after the car is driven for a good while and restarted shortly afterwards the speedometer and gas...


The problem I have found on all models that experience gauge malfunctions 90% lead back to the ignition switch. The most used part in the car. What I have found is it is totally intermittent. Reason being that the switch has to heat up to malfunction. I couldn't guaranty this is your problem, but I have resolved alot of gauge problems with replacing the ignition switch. Hope this helps you and your mechanic

I recently bought a 96 dodge caravan. The guages are not working. I the fuse is good could not find any disconnected wires. When the ignition is turned on the guages jump. Could the problem be the ignition...


Check and Reseat every fuse you can find, on-by-one. It's amazing how often this does wonderful things. ;)
Make sure your battery is good, and has a good charge and good connections. The gauges are all computer controlled, and computers don't like iffy or dirty power.

But, the most likely culprit is the BCM (Body Control Module), although I've seen this caused by bad solder joints on the gauge cluster connector itself.

This can also be cause by a bad PCM or TCM power/transmision control module), but if the van starts and runs, it's very unlikely.

A quickie test for bad solder joints that works about 3/4 of the time is to simply whack the dashboard above the gauge cluster with the engine running. If the gauges jump, (not just wiggle a bit) it's likely you have bad solder joints.

Try holding down odo trip and reset buttons on the gauges. Turn the key on while holding them down. If nothing happens after 10 seconds, it's probably BCM, but still could be bad solder joints.

If you get 'codes', then there is hope to narrow it down:
110=Cluster mem fault
111=cluster calibration fault
905=no TCM comms
921=odometer fault from BCM
940=no PCM comms
999=end of tests/codes
chec-0 will dim the display
chec-1 will move all gauges through their entire range
chec-2 is odometer light test

When you see chec-3, keep your foot on the brake and move the gear shifter to each gear, give it a second in each position while you watch the display.

Also, if you have a compass/trip computer overhead, I've seen them cause problems. Disconnect that console and try again.

Jeep cherokee 1998--After replacing steering wheel and original air bag the' air bag' dashboard light keeps on and also 'check gauges' light comes on and off. do i need a new air bag or is there a cheaper...


well the check guages and airbag lights are most likely not related, the airbag is most likely the clockspring contact under the steering wheel is defective, check guages means you have a gauge that is reading a problem like low oil pressure or overheating, this can be the body control module causing this as well..

2003 Cuts off when hot, will not start untill cool


My 2003 nissan sentra would get hot and stall out even in middle of highway doing 70 mph. The guages would go up and down. Would not start up all the time after stalling. had to cool down first. Nissan said it was head gasket, and wanted to charge 1000.00 for the job. I took to local dealer who charged me 550.00. Works fine ever since. Nissan dealer said they do like 3 head gaskets a week on the sentras. They have crappy ones in original parts. They have not recalled though.

Temperature Guage, '89 Camry


the cable going from the gauge to the sender unit is an earth return. if you take it off the sender unit wire if the gauge does read hot the sender and earth it out the gauge should go to the hot segment.dont leave this cable to earth very long do it quickly. if the gauge does read it is ok, there is no earth to the petrol tank. if it does not read it will be faulty. hope this helps.
