I have a 98' TL 2.5 , 144K miles, riding down the road and the radio stops. Interior and glove box light are out, power window will not go up when car is off and the ding-ding sound you get when you leave your light on or keys in and open door. Checked fuses and they looked good. Any help!!

 

Simple, you have an electrical problem, get the manual, check your fuses and wiring as well, if you hooked up the radio yourself check to make sure no wires are exposed.

 

Could this get expensive being an electrical problem?

 

yeah it can be if you want it done right, my best advice is to make sure you connected everything right and test it and also make sure your battery is in good standing, but you really must get that checked tho...
