Default DIY on changing/cleaning cabin temp sensor

the directions to remove this start at post # 7 since when i posted this i wasnt sure what it was and had already take it apart/out

im just wondering....someone told me to take it out and clean it (which i did and man was it nasty) and it might help with my ac/heat issue but i dunno wtf this is or what it does....it's a little hole above the drivers pedal on the kick panel...below the ignition! kinda square shaped and it seems to pull a vacuum when the air is on

ok this is the sensor



this is where it sits behind on the kick panel


this is the hose it goes into


everything you need to remove to get to it





future projects to come (more DIY'S) JUST SOME TEASERS







MY 2 BABIES ON THE PASSENGER SEAT

It's the cabin temp sensor for the "auto" mode. It senses the cabin temp and adjusts accordingly to the set temp when in "auto" mode.

Brian add some verbage and we can add this to the DIY section. I thinks it will make a great addittion. You already have the pictures just edit in the words as needed.

Let me know.

How did things work out with the nav stuff?

Thanks

im really not sure what difference this thing does i was just told its part of our hvac system and now i know what it is/does but i will clean it up for the sticky nigel. it really wont do much but if ne1 ever wants to change/clean it it will be helpful. OMFG guys i almost bet no1 has cleaned/changed it and man this thing was DIRTY

....oh i got some more coming soon for the sticky pics taken just waiting on my lazy or busy *** to do them and since our servo now blocks photobucket its gonna take me a min

...nav stuff is worked out. but between having to pay the irs this year and the fact that my company started laying off today im on hold with ALL mods....

u been hiding lately nigel?

ok i tried to get on last night but it seems the site was having issues as i could access every other website i went to but this one

1st step: start by popping the ignition cover off (i didn't use my key i just forgot to take actual pic) use a butter knife (NOT A FLATHEAD) or if you have one a interior/panel puller (audio shops have/use these)



2nd step: pull ignition cover piece downwards it will just unsnap....its held on by 3 prongs



3rd and 4th step: simple Phillips head screws




5th step: simply unscrew bulb (just twist it and pull it out) then push obd II port out....it has 2 clips on backside


6th step and 7th step:i forget if these are 10mm or 12mm just unscrew these. im pretty sure they are 10mm though




8th step: again i forget if these are 10mm or 12mm just unscrew these 3 bolts. im pretty sure they are 10mm though

9th step: i forget if this is a 10mm or 12mm just unscrew this. im pretty sure they it's a 10mm though



10th step: unhook brake cable from this clasp (sorry crappy pic)



11th step: slide brake cable out of this hole



12th step: pull panel out now and you'll see this still attached



13th step:unplug the plugs with the red arrows.....IT IS NOT NEEDED TO UNPLUG THE ONE NEXT TO THE BLUE ARROW so i just didn't do it



14th step:you'll see this section hanging down on the other side



15th step: unplug this plug and then unscrew sensor



16th step: use a contact cleaner or a electrical parts cleaner to clean this. i used a product called CBC II (circuit board & contact cleaner) we sell at work. (i used q-tips but not sure if this is best thing to use as they can leave fibers) don't spray directly on sensor but up tube and in top of cleaner than swab q-tips in it and clean tube,sensor,housing, etc

when putting back together just do the steps in reverse....this is ALSO a good time to change that floor light over to a LED light like i did.....




the bulb # is a 74. i ordered it from www.v-leds.com use the code club lexus for 15% discount. this is the bulb i used http://www.v-leds.com/Shop/Control/P...id/0/SFV/32481

but if i had to order them again and i still may (thats the OCD side of me) i would get these
http://www.v-leds.com/Shop/Control/P...id/0/SFV/32481

again if most of u havent done this i would be willing to bet yours is FILTHY

enjoy guys........

It's near the driver's right knee. Small panel with horizontal bars.
Remove the lower under-dash panel from the driver's side and remove the sensor by hand.
