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.
@@williampipkin5975 my 87 is doing it intermittently might work ok for a month, might not work the next day start driving boom its back on. think this will help. but yes it does temp and gas gauge together
Got the exact problem in my exact same red 1986 Toyota 4x4 Pickup. THANK YOU!
Im going to try this. Sometimes my gauge doesnt work unless i smack my dash a few times
Will the resistances spec in the service manual show bad prior to cleaning the contact areas as described?
I'll give this a shot, my guages only go up 1/4 the way. Also, none of the lights turn on.
Got the same problem on my 86 4runner
Gotta try this.
When this corrosion happens will both the temp and fuel gauges not read?
