Do you have the drivers side power window regulator assembly?

Be careful about taking the Lexus fuse listings in the owner's manual as a sure diagnostic; often they don't tell the whole story. I have a 1995 SC400 for which the lighter was out and found fuse 14 to be open. It's a 15 amp (blue) located on the driver's kick panel (check the manual diagram for fuse locations). I've discovered that in spite of the assignments in the manual several fuses may affect various other components as well. I got a clue about this by reading this forum - it may be a good investment in time to simply check every fuse in the panel whether or not the book says it has any connection to the problem. P.S.: There's a factory fuse puller stashed inside the lid of the large under hood fuse box (if someone hasn't removed it previously) that comes in very handy for pulling and checking the fuses while standing on your head in the floor board. BTW, one reason the lighter fuse blows often is that the lighter faces upward so any object such as a penny or paperclip that falls into the ligher socket while the lighter is out can cause a direct short that draws heavy current for extended periods. The fuse is there to protect against that heavy current draw scenario. Thanks, I will check all the fuses when she is home again.

My daughters 1995 sc400 also has a problem with the climate control system. When turning the temp adjust knob the temp will count up from MAX COLD through the 60's but skips randomly up to about 71 degrees (it should count in 1 degree increments) then starts counting back down even though you are still turning the knob hotter. She can't get heat in the winter, she said it used to count up by 1's until it said HOT.

The lighter socket on my daughters 1995 SC400 doesn't work. I checked the owners manual and the fuse for the cig lighter is also used for the instrument panel lights, SRS airbag and some other things that are working fine so I figure it can't be the fuse. I checked the socket with a meter and it doesn't have the 12VDC that it should so I am at a loss. any ideas? Thanks!
