Trying to figure out which fuse goes to the dashboard and the radio in my 2005 Infiniti Q45. Any help would be greatly appreciated! TIA

Well, first of all that 15V thing you are removing is not a spark plug. It is a fuse. If the fuse versus sparkplug thing is challenging you may need a little help identifying a relay. But, and I am not a mechanic just a average guy, find your fan. Find the wires leading away from the fan going towards your wireharness junction. The relay shold be along the way. It iwll look like a block, pretty small, smaller than your fist, plugging into a connector with wires. Look carefully with a flashlight at the connector and relay. Carefully release the clips holding the relay into the connector. Take a crayon, yellow and make a line from the connector over therelay so you can put it back easily, most only go back one way but you never can be too catreful. Gently twist and pull the relay out of the connector while twisting being careful not to break wires of the connector. When the relay comes free take it away from your Q45 and get some alcohol and some Q-tips. Gently clean the relay prongs, the things that stick out from the relay, metal, and don't use too much alcohol. Let the relay air dry for a minute or two. Put it back together. The TCS module is way over your head. Go to a trusted garage. If the unit is bad surf the net and shop for a new one to make sure you are not getting ripped off on the price of the part. Ask to see the labor hour estimate onb his computer as well. They may charge you a bit to diagnose the problem...sorry but that is life. Love your Q45 and it will love you back. I have a 95 Q45 with 187,000 miles and expect to have it go at least 300,000 miles. Great car.
