gauge cluster not working
Tachometer speedometer alternator voltage and coolant temperature are not working but fuel and oil pressure are still woking
---AutoMerged DoublePost--- Anyone? Please |
Well i'm looking at my book for your truck,mine is just 3 years older.
As for your tach,the book says it's tied in with your pcm(powertrain control module) as for the speedo,your vehicle speed sensor may have gone out. As for the alternator,i would also lok at the pcm. It's just wierd that those four are the only ones out, take a look at the fuse panel in the engine compartment.You may have some fuses out,or fusable links out. |

Anyone know how to test pcm or know what else my problem might be?

with my 7.3 i took the pcm out and took the bolts out and split it in half and if you get a flashlight you can look for burnt out connectors and such or any un normal sighns when you pop it apart. im sure there is a more official way of doing it.. but dealers want a shit ton of money just to eveb touch the pcm

Fixed it ended up bein my gauge cluster
