Air con blowing cold on one side of the car

[joelfigueira]

Hi all,

So today we finally get a warm day in the north east so I put my air con to cold for the first time. (I run my air con all year round) however when I was expecting nice ice cold air I was just getting cold air compared to the passenger side that was getting all the nice ice cold air. Both sides were set to low but only one side gets the ice cold air.

 

called Lexus Teesside who said it could be the Air mix servo that could be sticking and not going down all the way to low. 

 

Has as anyone experienced  this issue before if so did it cost a lot to get fixed or is there a hack to reset it?

Regards

The Lexus air mix servo's do seem prone to issues so it's not a huge leap for your issue to be related to them.

The servo's worm gear can become loose, DIY fixes are available online. 

Having looked at how my air box works, one of the links getting stuck seems entirely plausible.

My passenger side temp output is a bit off and I doubt I'll ever have the courage to look at it again.  Operating in dual mode helps alleviate the issue somewhat.

I may ask Lex-TexAuto's to have a look IF they're able to understand the conundrum, should I ever have them look at my car.

Good luck and let us know how you get on.

So I have contacted Teeside Lexus and the car goes in on the 30th April

 

if it’s the servo then the job will cost including the part £280 to £300 but if it’s the heater matrix it’s a dash out job and he said about £1000 to get that done.

 

im hoping it’s just the servo as I say it’s blowing cold out of once side and when I turn on heat all produce heat.

 

will keep you all posted

So it turns out the air mix servos were fine however the dash board had to come out to check the air con / heater matrix which is a 4-5 hour job and with labour being £125 + VAT the unit needed a good clean since dust and muck had stuck to the grease on all the moving parts.

Work all carried out and air con gassed just in time for the hot weather.

 

health check and car washed as standard.
