Replace transaxleoil with other clean

I take help from online websites that have this service like helping in repair some like reliable-store have instant help.. others are a bit slow which I don't prefer... re st is up to u.. U can also get free manuals

Easy, take the variety of parts out of teveaybamdbthebrenove the fuel rail, remove. Old inhjextorband replace with a new one, you'll get it!

Not a fuse issue , more then likely a burnt heating element in the seat , happens all the time . Heated Seat Components The heated seat system consists of the following components: • Driver and passenger heated seat switches • Driver and passenger seat back heater elements • Driver and passenger seat cushion heater elements • Driver and passenger seat back temperature sensors • Driver seat module • Driver door module • Passenger door module The control module have a Battery voltage supply , the module supply's voltage to the seat heating elements . The heated seat switches are momentary contact switches and are inputs to the driver and passenger door modules. Battery voltage is supplied to the switch assembly from the door module, and when a heated seat switch is pressed and released a brief switch signal voltage is supplied to the door module. Whenever the door module receives an active heated seat switch input, the next heated seat operating mode is determined by whatever the current mode may be. The seat heater elements are controlled by the driver seat module using inputs from the door modules through Class 2 serial data circuit messages. The driver seat module controls the voltage supply and the ground circuits to the seat heater elements. When a heated seat function is commanded active, the seat module will switch battery voltage to the heater element supply circuits, and ground is provided through low side drive control circuits. During heated seat operation both the seat back and cushion heater elements are supplied battery voltage. The seat module grounds the appropriate control circuits for back only or back and cushion heating modes, and opens or closes the active control circuits as necessary in order to maintain the desired seat temperature. The seat module relies on inputs from thermistors located in the driver and passenger seat backs to control heated seat temperatures. The thermistors are 2 wire sensors supplied with a 5-volt referenced signal circuit and a low reference circuit from the seat module. Resistance through the thermistors varies with temperature causing the heated seat sensor signal circuit voltage levels to decrease as the seat back temperatures rise. The seat modules allow heated seat operation only while the engine is running which is determined by a Class 2 serial data circuit message from the powertrain control module. Your best bet , take it to a qualified repair shop.

Get spare what ?

Look for the neutral safety switch , usually they are on the steering column under the dash but in this case it will be with the shifter in the console. If this is not it you may have upset the anti theft system which will kill the engine when its put in gear. the anti theft system is looking for a certain voltage and resistance, if that is disrupted it will kill the engine.

It is sensor. Censor means an official who examines material that is about to be released, such as books, movies, news, and art, and suppresses any parts that are considered obscene, politically unacceptable, or a threat to security https://www.yourmechanic.com/article/p0154-obd-ii-trouble-code-o2-sensor-circuit-no-activity-detected-bank-2-sensor-1-by-jamahl-walker https://repairpal.com/obd-ii-code-p0154

Have it scanned for DTC'S - diagnostic trouble code's . With all the electronic systems on newer vehicles ,that is the place to start , not just replacing parts . VSS - is a input to the PCM/ECM - engine computer , the PCM sends this info over the class 2 serial data network . Speedometer The IPC displays the vehicle speed on the analog speedometer based on the vehicle speed signal from the PCM. The PCM converts the data from the vehicle speed sensor to a 4,000 pulses/mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 km/h (0 mph) if a malfunction in the vehicle speed signal circuit exists. Need a factory or professional scan tool to diagnose , not just replace parts , (GUESS) Your best bet , take it to a qualified repair shop. Needd

Remove the plastic caps covering the legs and the bolts into the body once you remove plastic covers caps you will be able to see the bolts clearly, carpeting might be camouflaging both sides. And on a side note when removing chair make sure you disconnect the electrical clip for the seatbelt indicator

Look under the vehicle for the sunroof frame drain tubes and blow them out with compressed air.....

Neutral safety switch, try turn the key on neutral, jiggle the shifter, shift thru it's range, it may have come unplugged, or an alarm cut off relay or such.

Dimmer switch is bad , maybe . Did you try replacing it ?

No fuse , sensor make own voltage The vehicle speed sensor (VSS) provides vehicle speed information to the powertrain control module (PCM) or transmission control module (TCM). The VSS is a permanent magnet (PM) generator. The PM generator produces a pulsing AC voltage as rotor teeth on the transmission output shaft pass through the sensor's magnetic field. The AC voltage level and the number of pulses increase as the speed of the vehicle increases. Output voltage varies with speed from a minimum of 0.5 volts at 100 RPM to more than 100 volts at 8,000 RPM. The PCM/TCM converts the pulsing voltage to vehicle speed. The PCM/TCM uses the vehicle speed signal to determine shift timing and TCC scheduling. . What code # P0 what ? What speed sensor ? VSS - vehicle speed sensor , wheel speed sensor ? No diagnostic code tells you the sensor is mess up . Sensors circuit's can set a number code's lo voltage , high voltage , short to ground , open circuit . Your best bet ,take it to a qualified repair shop.

what do u mean by clears out?

use any 12v battery charger with current less than 6 amps current so that it wont spoil battery. u can easily find online or any auto store nearby

use compressed air to clear the tracks and then so with a brush and gas to remove grease and hard settled dirt, once its clean, then lubricate channel with grease very lightly, and then the channels should be moving much better, repeat if still not 100% satisfied or say after 2 weeks, would be better. thse r typical sunroof problems u face with alomost all cars with sunroof after few years of usage.

its in the centre part of seat, between the 2 passengers, where u sit and face front. its a plastic thing, so u can identify

most probably, your car battery is totally dead!! change or charge battery and thern try, should work

drain pipes are blocked due to which rain water is not removing by self, u need to use high preasure compressed air to clear drain pipes located on both right front sides of sun roof. once blockage is gone, then u wonr face this water logging issue
