On most vehicles there are 3 blinker bulbs on each side. One at the front corner, one at the rear corner and a third side repeater usually mounted in the front wing, (fender). Some more modern car companies have started fitting the side repeater into the door mounted 'wing' mirror body. The blink rate will usually be around 60 to 120 flashes per minute. If the rate on yours is usually slower, a higher speed flash suggests there is a blown or missing bulb.

DTC P0877: Transmission Fluid Pressure (TFP) Switch 4 Circuit Low Voltage The transmission fluid pressure (TFP) switch 4 is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The TCM supplies 12 volts to the TFP switch 4 on the TFP switch 4 signal circuit; the TFP switch 4 has an internal case ground. TFP switch 4 is normally closed, Low. When oil pressure is present at the TFP switch 4, the switch is open, high. The normally low clutch pressure control (PC) solenoid 4-5 controls the transmission fluid to the 1-2-3-4 clutch. The TCM monitors the normally closed TFP switch 4 signal circuit to determine the 1-2-3-4 clutch status. P0877 The TCM detects that the TFP switch 4 signal voltage remains low, 0 volts when the 1-2-3-4 clutch is commanded ON for 5.5 seconds or greater. Action Taken When the DTC Sets • DTCs P0877 and P0878 are Type C DTCs. • The TCM freezes transmission adaptive functions. Circuit/System Testing Ensure the TFT is near the temperature displayed in the Failure Records. Start the engine and place the transmission range selector in D6. Observe the TFP switch 4 parameter while commanding 4th gear and then commanding 5th gear with the scan tool. The TFP Switch 4 should transition from High in 4th gear to Low in 5th gear. ? If the TFP switch 4 parameter state does not change, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection . ? If no concerns are found, replace the control solenoid (w/body and TCM) valve assembly. Component Testing Perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection . Repair Instructions Perform the Diagnostic Repair Verification after completing the diagnostic procedure. Control solenoid (w/body and TCM) valve assembly replacement - refer to Control Module References for replacement, setup, and programming. Perform the Service Fast Learn Adapts

My personal suggestion would be to go for these repair catalogs. I know this website www.reliable-store that i used to buy them from, and they sold online it was very good manual. Go ahead, I bet.

There should be a lever at the base which allows the seat to fold forward then a secondary latch unlocks the pivot to allow removal. If you need further help, reach me via phone at https://www.6ya.com/expert/james_8f14c50d9c6cdea8

Replace the passenger side blend door actuator

Controlled by a control module ,BCM , liftgate module etc.... Probably a switch input is bad . You don't say what year ,but doesn't matter .your best bet , take it to a qualified repair shop.

Could be rusted and broken because have others codes you should check for new codes.

When a car will not run right after refueling, it is usually the vent valve, that vents the tank. If not opening, then using a small amount of gas will create a very strong vacuum, and not allow the car to run. Try cracking the gas cap a little, to let air in and reduce the vacuum. Automotive Evaporative Emissions Part One

Can you drive to auto zone to check codes? It is free then we can start looking for problems.

No, but it is a lot of work. Might have to drop the engine frame/support..

this is the part .. looks like one of the harder diy jobs on this model take photos as you go you need to be able to undo all the clamps and connections and put the hoses back in the right place source internet one mechanics view on the job Spent the better part of two hours pulling this hose out of a customers car. Had to drop the alternator and starter motor to get enough room to pull it out over the gearbox. did you pull the inlet manifold or drop the alt and starter like i did?

What is wrong,any codes?
