DIY on changing servo motors
ty. although this actually wasnt that hard. the pics should help people be more comfortable with it! yes, probably. UNFORTUNATELY the drivers servo that controls the drivers heat/air is a PITA to get to, it according to the repair manual it reuquires removing the dash, steering wheel etc (although i think you can get by with just pulling the dash out some....to gain access to it)

) and putting this one off...
i dunno i think dealer charges like 200 a servo and 3-4 hours labor so assume 100 a hour....bout 600-800 i guess would be a resonable idea. MAYBE 500-700 but i doubt it. dunno bout u but y would i wanna pay that when parts only cost me like 300 for the parts?

ok guys for the most part this should fix all your problems but i have run into a strange one again....
ok so i ordered some "used" servos awhile ago from a member, sent them back after i got them as they still wouldnt engage the foot mode....so i installed the new ones straight from the bag i got from sewell lexus. GUESS WHAT? THEY WONT ENGAGE INTO FOOT MODE EITHER...when i put it in feet/face mode it turns on face + defrost, when i put it on feet mode it goes just to defrost BUT if i drive around for 10-20 min SOMETIMES it will finally kick into the foot mode. i have watched all the servos (yes EVEN the drivers side, although i didn't pull the dash i just removed that black plastic foot piece and watched it engage) so i know they ALL are working but i still cannot get this to go into feet mode.....
i did run a diagnostic and am showing NO codes....put it in test mode on mode 6 it runs partly on feet but mode 7 it will ONLY run top defrost and#7 is a feet test mode. i even opened the ones i took off the car (yes nigel i'll get you a pic
and they are all good....NO broken teeth on the gears, still have plenty of grease)
anyone have ne1 ideas? my mechanic said these units need to be calibrated but i have NEVER heard of these having to be calibrated, so before i take it to the stealership (where they are gonna tell me i need to replace my mode servo) can someone help me out here? ne ideas or suggestions?

WOW! Brian that stinks! I know that you have been working hard to get this fixed.
I hope someone can chimes in and give you some insight. Hey man don't worry about the pics I think I will just replace them so it's cool. Keep me updated. 
Did you get the parts for your sunroof?

no nigel no parts for the sunroof yet, it functions fine just has a broken arm and since im not using it right now, im gonna address my other turmoils first but again ty so much for the info on the craigslist post i do have another DIY up my sleeve as soon as that gets here....another one i havent seen yet

if ne1 can also help, im looking for some help on this too....or a confirmation before i invest into a nav comp
https://www.clublexus.com/forums/gs-...direction.html
i would say the nav IS more pressing BUT im tired of having the glovebox outta my car. it looks like chit and i grow old/tired with these nuiscances. someones gotta be able to help me
they do need to be calibrated. i dont' know if this will work with a nav system, but this is how you calibrate on a non-nav.

my mechanic mentioned but i said i didn't think so cause in all the posts i have read, i have never heard ne1 mention the word recalibrate or something like that when they were talking about the servos. i wonder if this was my inital problem and i bought servos for nothing......or nothing more than to make a DIY for others

i will try it tomorrow when i get a min! thanks again at least it was some info even if it doesn't fix it...lets just hope it does
now if only i can get someone to chime in on my nav i might start having a decent week/month/year

well this didnt work
so ne1 else have ne ideas or is there a different calibration for the ML systems? i spoke to dealer earlier and my parts guy actually let me talk to a tech and he said he's not aware of ne calibrations on this car??????? is he retarded or am i missing something....? we also might be looking into the possibility of a it being a heater/ac control head unit! between my nav computer and IF its that part im looking at atleast 1.5-2k OUCH

cooling servo lets car go into hot/cold mode. besides the noise what kinda problems u having?

new servos (done twice once with used servos and once with new ones) and i picked up a used climate control assy off ebay from a member on here actually thanks shawnberry
although his is in great condition compared to mine (all his bulbs work) it still didnt fix my issues...
so i found out a buddies shop picked up a lexus electrical specialist and im gonna take it to him
i think i'm gonna end up finding out i didnt install the servos right or something stupid! will update again l8r
