no its not!! dammit!

i just came back from junkyard. tried another tcu and still not working!

but wait is there a different between the the tcu with E and DE? cuz i tried both no luck.

checked and replaced fuses and covered all wire from audio. got sparks that why i a fuse went out! wipers work too. check the dimmer switch/cluster/tcu wires and the parts too.

how did you check the speed sensor?

you'll have to remove the sensor from the transmission. spin the pinion and measure the voltage across bolt wires. you should have 0.5v.
