Oldsmobile 1993 regency elite ...when I plugged in the cigarette lighter suddenly the radio, the heat and the AC quit working. Seems to me to be a fuse problem but there doesn't seem to be a fuse that covers all 3. Is it the circuit breaker? How to diagnose & fix?

Then the belt wont fit, and no other belt will fit either. What you can do is buy a "bypass pulley" , also called an "AC delete pulley". You take the old AC compressor off, and fit a free wheeling pulley onto the compressor bracket. Check with parts stores or google it for an online picture and explanation.

Check the fuse box there is one for radio but sometimes lighter shares the same fuse as radio.

there is a ctsy/clk fuse that runs the lighter and memory of the radio, did you check that one?

I have a 1992 /98 0lds the air condition will not work unless I take the ground wire lose then it kicks in but it show that makes car is over heating when it is not what sencer is doing this please help [email protected] it is hot in texas

More than likely overheated the wiring going to the lighter as well and burned it off. If you pull the lighter socket out you should see if it did. Simply solder it back on and be careful not to overload it again.

THE FUSE BLOCK IS EITHER LOCATED UNDER THE DASH ON THE DRIVERS SIDE OR IN THE DRIVERS SIDE ENGINE COMPARTMENT. IT WILL BE MARKED HEATER.

You need a blower motor resistor.

Check the fuse box under the hood, one of them should be blown

I assume that you tried the cigarette lighter itself and didnt rely solely that the charger was working properly. When you tightened the ring on caseing did you see that the wire connected on the back of the lighter was properly attatched, sometimes a good connection loosens up especially if caseing was found to be loose.. Well assuming it was properly connected you could test the circuit with either a multimeter or 12 volt test light if power is found at connection then you problem is definetly the cigarette lighter assembly itself.. I hope this was helpful...Let me know I would appreciate it

your cigarette lighter works off of a fairly high amp fuse check all your high amp fuses to be safe from 20 on up and chances are youll find the one. good luck
