Tyres replaced – Oct 2014
This was an immediate requirement; I advised my friend to go in for the OE tyres viz. Yokohama ASPEC A348 in 215/60R16. Four tyres cost INR 32,000 and the best of the four old tyres was used as the spare.

First Maintenance – Oct 2015
I am mentioning this yet again – some of my friends may be
de-jure owners but I would end up as the
de-facto owner and Chief Maintenance Advisor for most of their cars.
This car needed an oil change and I had the following jobs performed at 90,000km.
• Engine oil replacement – Castrol Magnatec 10W40 API SN
• Toyota genuine oil filter
• Air filter cleaning
• Spark plugs inspection – Iridium plugs
The air filter box on the Camry had bolts, unlike the quick release clamps that we see on other cars.
Total costs INR 3,640 Restoration of Power seats – Feb 2016
The Camry was saved from full damage in the Dec 2015 floods in Chennai because the car had been parked in an elevated parking. However, the elevated parking could not save the car from a low level flooding that had just touched the seat control switches. My friend reported that the seats were working once the water levels had receded but the carpet was wet. The carpet was cleaned out and disinfected professionally.
About a month later, In Jan 2016, he mentioned that the seats were not sliding back and forth or moving up and down. I was out of India and couldn't help him then. So as soon as I returned, I embarked on this project to try and get the seats back to working ways.
Observations
1. None of the adjustments except the seat back were working
2. Seat slide/ travel mechanism and metal panel were badly corroded
3. The driver seat has three motors below the seat - one for height adjustment , one for travel and one for lumbar support while the passenger seat has only one motor below the seat for travel adjustment.
4. Removed the seats and found that the wiring couplers for the seat motors and the seat airbags were intact
5. The seat adjustment switch panels showed sulfation (copper sulphate) and some contact points were missing.
Restoration of motors
Restoration of motors was performed at my FNG under my supervision.
1. The lowest motor under the seat is the one that controls seat travel back and forth
2. The worm gears , drive cable from motor to gear(resembles the inner cable of a motorcycle speedometer cable) and the motor inner bearings were all jammed.
3. Had the whole motor drive assembly, bearings cleaned with WD-40, re-greased with gel grease and boxed up.
4. Armature and commutator were cleaned with iso propyl alcohol. Carbon brushes were found to be in good order
5. Repeated the above for the other two motors (which needed some effort as their screws were not easily accessible)
6. Repeated the exercise for the passenger seat bottom motor which was equally bad
Seat bottom looked like this
Driver seat motors serviced and being fitted back
Restoration of the Power Seat Switch Assembly
1. The 4 way power seat switch assemblies of both the driver seat and the passenger seat were in bad shape - lot of copper sulphate had formed and some contact points had disintegrated.
2. The switch assemblies were not available locally, thus making it necessary to build the switch circuits again
3. We used contact points from a spare circuit board to repair the switch circuits , provided a copper contact plate below and soldered jump-over wires from the contact points to the nearest available 12V supply lines to establish continuity.
4. The seat slide mechanism needed some wd40 to help it regain its lost touch
Driver Seat main switch before repair - note the missing contact points
Passenger seat main switch after repair - the green indicates portions that were re-built

Results
1. Seats motors' wiring was coupled back
2. Motors were observed to work normal
3. Seats installed back and we were back to pre-flood days - voila
Total spend INR 2,500 ; this exercise took two full days and was a tough challenge , but we emerged victors !!
Just for reference - in the Camry, every motor under the seat costs INR 14,000 (making it INR 56,000 for four non-functional motors) and the three power seat switches were listed at a total of INR 17,400.
Two days of effort saved my friend a potential INR 71,000.
Expenses from 2014 to 2016
Break up of expenses on the Camry in INR was as follows:
A: Capex INR 32,000
1. Tyres Yokohama ASPEC A348 INR 32,000
B: Maintenance INR 3,640
1. Oil (Castrol Magnatec 10W40) + Oil filter + spark plugs inspection + Air filter cleaning + Wash INR 3,640
C: Flood Damage INR 6,300
1. Seats motors and switches restoration INR 2,500
2. Carpets disinfection INR 3,800
Total expenses A+B+C INR 41,940 Current Status of the Camry
The Camry has been retained in my friend’s family and is still soldering on, true to Toyota’s tradition of its cars keeping the owners happy. I've lost track of expenses and records on this car since 2016 but what difference does it make as long as the owner is happy.
The Toyota Camry is as much of a
fill-it-shut-it-forget-it car as the Corolla, as long as the car is kept well and does not need unforeseen expenses like in floods.
