How to replace ignition switch on 88 cadillac deville

SOURCE: unable to insert key into ignition switch

Try this pull the steering wheel as far to the left as possible and while it is in this position try to insert key. Sometimes the steering wheel lock will get in a bind and prevent the key from being inserted. Hope this helps!!!

First do you have a sterring wheel puller. Can't remove the steering wheel without one. Quite an involved job including snaking the electrical connector end through the steering column. I wouldn't recommend it to the novice

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.

try turning the steering wheel to relieve the pressure that might be exerting force on the steering wheel lock and make sure car is in park

Look for a plastic plug directly under key in bottom of column. Under plug is a switch take small philips screwdriver & push on switch while turning key backward to take out.
