What's inside power window switch

For a long time, the power window switch are intermittently working for left front window.
Decided to buy a replacement. When got the replacement switch, the switch are not interchangeable. There are slight different between AE111 and AE110 switch.

So can't change it. Then I've decided to dismantle the power windows switch, if lucky I manage to repair it.

A circlip that hold a pin for the cover of the switch.

After remove cover now can see the switch button

Removing all the upper part will reveal the copper circuit. Noticed that a burned mark when the circuit closed. After using it for more than 10 years, the contact pin are not in proper shape anymore. That's why it got intermittent problem.

What I did it reshape the contact pin to a suitable shape, so when push/pull the switch both contact pin are touching the base.

The whole power window switch

Cental lock changed in AE111

 Fisrtly remove internal door  cover  which I've not shown here.
Then remove 4 screws at the door as in the picture. 3 screws for door lock assy and a screw for a glass sliding guide.

Here is the picture of the door lock assy with all links labeled.

Unscrew inner lock to release the link to lock assy.

Remove clip that hold link for outer handle and remove the link

Release clip that hold link for inner handle and remove the link.

Release clip that hold outer key lock and release the link.

That's it. now you can remove door lock assy and replace it. Install it in reverse order.

GPS FIX for Google Nexus Jelly Bean

Since my first android which was a fascinate i I have obsessed with The gps . Finally I managed to get the correct setting but it was time for an upgrade ..Out of the box I was very disappointed with the how long it took to get a GPS lock on my GN ..So after doing my homework and and trying out a few different apps and settings I Finally have it down to a science where I get almost and instant lock !. There is a handy little free app called "GPScompassMap" that you can get at the market . It is an accurate app that tells you how many satellites you are locked into . Before you change your Gps settings do a test and see how many satellites you are locked into .. If your not getting between 8/8 and 11/11 then this is for you !Of course make a backup .
.
The only settings that will be effected are your GPS settings .


Please click "Like" just so I can see how many people these settings are working for.
I am not sure what that "Vote" button is for but it wont hurt to click on the "Vote" button too 
By the way you will never have to purchase another GPS app again . I am not asking for donations ..Just click like or make a comment .. 


For some reason for the most part "angy GPS" is not opening up for a lot of people .This app is not a necessity just a tool . you do not need any apps for this configuration to work . By the way people are reporting that this is working for everyone not just CDMA .. Once again make a backup and enjoy your tweaked out GPS settings ! 
Thanks ,
Mitch

Here is the flashable zip file ! UPDATED ! AND YES IT WORKS ON JELLY BEAN 4.1 !

Lots of ISCV picture

Intake air temperature with hot air shield

After I've installed intake hot air shield, I've measured again the intake air temp.
Surprisingly that the intake air temp is significantly reduce. The temp reduce more than 10 deg Celsius when at the toll and temp also take lot of time to ride to max.

So it's very big improvement by only install a shield.

Go to : Hot Air Shield

Air Intake Hot Air Shield (2nd Attempt)

This is my 2nd attempt for air intake hot air shield. 1st attempt is failure where air are too restricted and engine choked. If this success, I'll make another shield with better materiel.

Go to : Intake Air Temp Measured With Hot Air Shield

4age20v ISCV CAI trick

Before this I've recorded air intake temperature at different time and different place. And here is the result.

I've never taught temp that feed into combustion chamber is that high. So I am thinking how to feed lower air temp into combustion chamber.

Then I got this idea. 

Make a CAI (cold air intake) for ISCV (idle speed control valve) and split the ISCV intake from main intake hose.

Original condition of ISCV is same as below.

Then take another hose to make individual hose to feed air to ISCV. Put the end of the hose in front of the engine to avoid hot air from engine bay. Modified hose is as below.

Actual picture for the CAI that I've install is like this.

Ignore the cheap water hose that I've been using. This is for temporary testing. Probably I'll replace to a better hose later.

As far I've been using this mod, I can felt better throttle response coz lower intake air temp are feed into combustion chamber.
