it should b a simple fix if ur willing 2 do a bit of work. get in behind the lighter as mentioned and check the connection...ive seen those things loosen over time . also check for power and ground using a circuit safe logic probe. i just put a cig lighter in my car last week that i bought at canadian tire 4 8 bucks cause my 00si came with an optional lighter and im a smoker...thats TIGHT! i only use it 4 my phone and pc
