If your Lexus RX 300 cigarette lighter will not remain in place when pushed inward, there are a few steps you can take to repair the problem. You can fix a cigarette lighter for a Lexus RX 300 as a do-it-yourself project, but if your efforts do not solve the problem, you should take it to your local Lexus dealership for repair service.
Retrieve your manual. Then, check the fuse box. The fuse box of a 2001 Lexus RX300 is located behind the coin holder drawer, to the left of the steering column. Check your manual to see which fuses operate the cigarette lighter socket. If the fuse is blown, you will see a small, broken wire in the interior of the plastic shell of the fuse. Replace a blown fuse with a fuse rated for the same amperage.
Pull out the ashtray to gain access to the lighter's wiring connector. The 12 volt and ground wires are connected to the socket. Also, identify an L-shaped wire that has a rubber coating. This is a fuse. Find the two small terminals at the bottom of the L-shaped, rubber-coated fuse. Remove the fuse, then bend a paper clip in an L-shape and place it where the L-shaped, rubber coated fuse was positioned. You should position the L-shaped paper clip at the end of the socket.
Remove the ashtray from its panel. Remove any small Phillips screws. Then, remove each spring found on the side of the ashtray.
Disassemble the lighter assembly or lighter housing, by loosening a hex nut at the bottom of the lighter assembly. To accomplish this task, the panel must be off. Then, reassemble the lighter assembly. Check to see if your lighter will stay in position when pushed inward.
Replace the lighter with a standard size cigarette lighter from your local auto parts store. If a fuse is not burnt out, and if disassembling and reassembling the lighter socket still does not help the lighter stay in, take your RX 300 to a Lexus dealership.
Explain the problem with the RX300 cigarette lighter fixture, and ask a Lexus service professional to inspect your cigarette lighter socket. The dealership should inspect your RX300 to check for any possible wiring or electrical problems.
