tHeWiFe Posted February 22, 2008 Share Posted February 22, 2008 A list of Gremlins currently experiencing: When I purchased the vehicle: *seat memory came with no function *power mirrors came with no function *have to manually open the trunk came with no automatic function Since purchase, had an after market alarm system installed.. however had the system disconnected to see if that might have been the mystery behind the new problems. No such luck. Starter problem now. Either the solenoid or the starter, checking this Saturday. Already checked, the starter has power running to it. However with a little patience, does start still. Battery cables fine, and cleaned, as well as coated. All fuses are fine, with the exceptions of no power to these two sections when tested: ST HTR (my guess is seat heater) as well as S T <~(no clue what that means). We have in our possession a 1992 LEXUS SC300 OEM FACTORY WIRING DIAGRAM MANUAL, with a little outside help, will start diagnosing this weekend. Here's what went wrong a couple of months after purchase: power locks inoperable:have to manually lock or use the key heater memory no more: always resets to off position when starting the vehicle. odometer memory resets power tilt wheel no function: worked perfectly, now not at all. dome light no longer functions rear view mirror on dim no longer functions vanity mirror lights no longer functions cigarette lighter no longer functions/light works fine passenger seat will not go forward automatically however the power seats still slide on tracks no memory vehicle no longer senses when doors are open or ajar Question Is their a common ecu involved here? perhaps something in the wiring? Additional problem: Happened this past week. All connections tested okay... except at one point in time their was no power to the St fuse area... starter... as well as no power to the st htr... seat heaters. Dash illumination tends to stay on after vehicle is shut down. Turn blinker "left" with quiet almost grinding noise under left dash shuts it down, since my doors have no working sensors. Aside from that being a bit on the odd side... here's an even more confusing thing.. turns itself back on intermittently while no one is in its proximity. I've disconnected the battery cable so it's possession will not scare the neighbors. Have an inkling it was a most recently cleaned ground.. checked it.. didn't seem to be the problem. Disconnected the Auto start/Alarm system..not the problem either. So, now sits in the driveway an interesting obstacle... Interior front completely removed until problems fixed. Any help? On anything? Quote Link to comment Share on other sites More sharing options...
GrnHrnt Posted February 23, 2008 Share Posted February 23, 2008 That many Gremlins can be very intimidating. Start with easier problems like dome light, cigarette lighter or vanity lights. Solve one problem and then move on to the next. Solving one of those may solve other problems also. Car has numerous ground connections and a corroded one can cause headaches with several seemingly unrelated systems. Also inspect larger connectors that handle many circuits. Has the car ever been partially submerged? Quote Link to comment Share on other sites More sharing options...
