My son's 87 does that. i replaced the sending unit when i put in new hoses, and thermostat. everything reads correct on the sending unit. i figured it has to be a bad ground somewhere. The both quit working at same time. I wonder if the fault is on the back of the instrument cluster.
Got the exact problem in my exact same red 1986 Toyota 4x4 Pickup. THANK YOU!
you helped me!
Gotta try this.
Im going to try this. Sometimes my gauge doesnt work unless i smack my dash a few times
I'll give this a shot, my guages only go up 1/4 the way. Also, none of the lights turn on.
Will the resistances spec in the service manual show bad prior to cleaning the contact areas as described?
Got the same problem on my 86 4runner
When this corrosion happens will both the temp and fuel gauges not read?
