1999 Millenia: I used portable air pump to inflate tires. Pump stopped working because cigarette lighter stopped working. Is it the lighter (if so, how do you replace) or is there a fuse somewhere (fuse box is under hood). Where can I buy parts.

Fuse 18 or 19

This can be because of a few reasons and the main one been there is a short with the wiring somewhere you would have to start at the cigarette lighter and try to work you way back to the fuse box or if you have a volt -meter or multi-meter you can check using one of them to see if you have a short , I am not sure of the fuse rating for your lighter but make sure you are using the right one ( probably around 25 to 30 amps) But as I said most likely you will find a short

It sounds like you might have drained your battery! When the car is running does the Cigarette lighter produce power? It should be working while the car is running. That would also explain why the car starts sporadically. Try leaving the car on for 40 minutes. That might charge the battery enough.

Looks like you overloaded and blew the cigarette lighter fuse while using a 12v tire inflator pump. Check the fuse and replace it.

yes you sure did ! check in the owners manual for fuse location . the safest way to use those inflators are with a cigarette lighter adapter with alligator clips right to the battery hope this helps

if you locate the fuse panel it should be marked either # 2-3 or accessories fuse marked on the cover

it is fuse # 1 in the fuse box under the dash on the drivers side it is a blue 15 amp fuse

did you use a test light this would be the primary source for an accessory not to work unless the wires to the connector on the back side of the lighter itself has come undone or it may very well be the ground to it you need to visually inspect it a mirror may be of assistance to have a look if you cannot bend under neath the dash maby you can remove the ashtray to better view it

change the fuse anyway,the test might show ok but often it will not pass a heavy current.try this first before you start pulling the dash out to get at the socket.

so you replaced a blown fuse to the cigar lighter and it still dosent work?.. then the wiring was compromised before the fuse blew..you need to repair bad wiring to cigar lighter and/or lighter itself internally melted /failed due to your air pump asking for more electricity than the cigar lighter could deliver..once repaired do not use the air pump there again ..good luck
