My speedometer will read zero no matter how fast im going, cruise control doesnt work, mileage doesnt add up, warning lights for ABS, air bag, check engine and service light all come on, gear indicator light flashes or turns red and stays by the D gear but flashes green by other gears while still red by D, A/C blows but not cold. ive noticed that not often at all turning on headlights, opening sun roof or front windows will "fix" the speedometer and A/C, but rolling down the back windows "fixes' the problem much more often although not always.
Start going overy the wiring harness looking for any rubbing. Sounds like an electrical short.
It sounds like you have a ground issue near the transmission. Make sure the ground strap above the upper radiator hose is booked down good. Also check the plugs on the transmission for a loose connection.

you need a transmission computer located in floor on passenger side under carpet attached to the ecu computer you can get one on ebay for 120 dollars ALOT LESS THE parts store and it comes with a lifetime warranty
SOURCE: heaters not blowing out any air
most likely the blower resistor is burnt out, this controls the speed of the air blower, low,medium,high. The blower and the resistor are located behind and to the right of the glove box under the dash on the passenger side, u will need various screwdrivers and a few different wreches t fix it yourself.

sounds like a possible bad ground wire, you will need to find out where these 3 items ground and see if they have a ground point in common.

It could be the computer, or the speed sensor. The speed sensor will control the speedometer, and tells the transmission at what speed to shift.
If it is the Transmission computer module (TCM/TCU) it will be located under the passenger side foot rest. Just pull the carpet back, and remove the steel panel cover using a deep 10mm socket. The TCM is usually the one on the left, but sometimes on the right. It will be the smaller of the 2 coputers. The other, is the Engine computer. When you locate the TCM, you only have to sets of wires that just snap in. Unsnap them, and you can take the cover of the TCM off with just a phillips head screw driver, and look to see if anything looks burnt out one the circuit board. If see something that looks burned, that is your problem, and will need a new one. It took me about 30 mins if that, to locate the TCM, remove it, and replace it.
If it is the Speed Sensor, you can find one online for about $21.00 at eparts.com Best of luck to you, and hope it helps. If you have anymore questions e-mail me at [email protected]
