Usually it's the opposite. The speedometer works and the odomater and trip meter go inop. Most likely the speedometer assembly is bad. If the odometer is working you have a signal from the gray and black wire .

I installed and after market stereo and my speedometer quit working 1999 chevy s10 blazer

Speedometer problem: This is well-documented on V8 and 200 models..Check here for info:

Dash lights: check the dimmer control knob first, then the bulbs..If not those, then it could be related to the problem above...

Driver's seat warmer; could be broken wires leading to the warmers inside the seat from, or the elements are simply burned out.

Blue smoke is oil related, not head gasket (which would be white)..Most V8's will exhibit a little blue smoke from time-to-time, but if it is excessive then it may be time for vailve seals or piston rings..depends on the mileage.

Yes your speedometer, and odometer are controlled by your speed sensor.

You should have a speedometer cable that runs from the back of the trani, thru the fire-wall, and into the back oh the gauge cluster.

speedometer cable? speed sensor or speedometer meter it's self! engine light on scan obd 2 to retreve codes don't gue$$

possibly dimmer switch
