I have a 1990 f150 and the gas gauge and cruise control don't work none of the other gauges on the dash work either. but all the lights and signal lights work too. I've checked all the fuses and they are all good. can anyone help?

 

If you take the faceplate off of the dash , you might find that you need to simply plug in some connectors from the display, or replace some wires or the whole thing. My guages stopped working and i ended up having to go to a junkyard and pulling a new display and harness, and now it works..

 

Thanks, I've taken the faceplate off dash and re pluged aii the conections back --still doesn't work ,did you say you replaced the harness?

 

Yes i did, it turns out that there were a few shorted wires, and the connectors were pretty corroded as well.

 

Mine had issues where parts of the gauges worked or none worked and mine turned out to be a gauge cluster (Got a salvaged on for $50.), a 25 amp on the fuse box, and having a $35 sensor replaced in the rear end to get the speedo working again.

Not sure if that helps any but thats what I had to do for my 1992 f-150 w/ 4.9L & 5 speed.

 

Thank you i'm off to the junk yard tomorrow.
