no tach or speedo

[DrMcDave]

i had them working fine yesterday amidst my dash swap, then i plugged the defroster switch into the AC plug by accident. this killed my headlight switch which i have replaced but i still have no tach or speedo. Its not a fuse related problem and its nothing with the back or my gauge cluster because it was work post cluster install. I have no idea what it could be.

Every other thing in my car works as i checked them all after the swap. I need help i really don't want to have to take my car to the shop.

the new dash looks so much better though.

check SI battaries, may have fried them.

[DrMcDave]

where are they?

also my fuel gauge and temp still work, is that possible with fried batteries?

sorry to bring this back from the dead, but I have the same problem.

I swaped dashes, installed the one one, pluged everything back up, but now my speedo, tach, MPG, and fuel gauges dont work.

I was wondering if you maybe have found what the problem was?
Any one have any sugestions?

Thanks

bump for similar problem

If your odometer also doesn't work, check your fuses again. I had that problem so I replaced the two causing the problem with 20s. Check them all again if you haven't already.

Well, I ended up somehow fixing the problems. All I did was disconect the battery for 15 min., and connect it back up. Now everything works, although I forgot to connect the defroster switch.
