SOURCE: 88 cadillac deville, ac blower fan wont shut off,
Ralph,
Most common cause of this is the blower fan (proper name for the fan you refer to) continuing to run is a shorted out Electronic Climate Control Module. This solid state device replaces the older style fan speed resistor block (at about 4 times the price) This unit is found on the top of the HVAC box under the hood. (HVAC means heating, ventilation and air conditioning) The HVAC box is found on the passenger side of the firewall. Look behind the A/C's accumulator. It will have an electrical wiring plug on top of it. It will be fastened to the HVAC box with a few 7mm hex head screws. Very easy to change.
FYI, do yourself a favor and replace the blower fan motor at the same time. The Electronic Climate Control Module usually fails because the motor is drawing to many amps of current. This is because it's bushings are worn out or the brushes are worn out.
This is very common on Cadillacs and Buicks.

PS Not sure why car won't start. Either you drained the battery or blew a fuse which controls starting the engine. Need more info regarding the "no start" condition.

ok, In this New of a vehicle there are no screws holding the headlight in if you just need to replace a headlight because it is burned out. Look at the back of the light where the wires attach and you should see the wires going into what appears to be a coupling. Get a hold of that and turn. After it unlocks you can remove and replace the bulb. If you are replacing the Headlight assembly because it was damaged there are typically 2 long scews on the top front that appear to be adjsutment screws and 2 smaller ones in each side, again on top. Good Luck

Have you changed the bulb on that side of the car? If a bulb is broken or burnt out it will not light up.

Here is a great write-up on how to completely bypass the VATS system including the Theft Deterrent Module (TDM). This is what saved my car: http://newrockies.ca/vatsbypass

I've got an even cheaper and easier solution, instead of buying a new cylinder, find that plug and snip the orange wires going to the old cylinder.Then remove the resistor chip from the key and solder each of the the wires to each side. this will fool the car into thinking the correct resistor chip is in place, allowing you to use the original key or any copies with or without resistor chips. i just did this to my caddy and it roared to life! :)

Can this happen from my car being wrecked in the front and air bags being deployed?
