I have a problem with my 2001 255004x4 leather seat heaters...They both began to intermittantly shutoff after being turned on. Id push the buttons again, then after a while, theyd go off...No flashing lights indicating a troubleshooting diagnosis capability-just off...Replaced the heated seat relay in the fuse box, no luck...Dash kights wont come on with headlight switch-dashlight dimmer doesnt work, either, but all other aspects of lights work-cargo, headlight, dome light on/off...Shop manual electrical diagram seems to show the seat heaters get their power from the dimmer circuit-replaced headlamp switch/dimmer module, still no luck...No 12v power to fuse #5-5 amp fuses on fuse #5 intact...also, no 12v to relay when key is on...????
