2002 ford expedition interior lights are not on what fuse is it?
Courtesy Lamps - central junction box. fuse # F1.21 that goes to interior lamp relay in the instrument cluster and F.24 this fuse powers battery saver relay .
Interior Lighting
The interior light system consists of the following:
- front map lamp assembly
- front door courtesy lamp
- generic electronic module (GEM)
- glove box lamp assembly
- central security module
- interior lamp switch
- interior lamp relay
- illuminated vanity mirrors (Navigator only)
- reading lamp assembly
- rear courtesy lamp
- running board lamp
- underhood lamp assembly
The generic electronic module (GEM) illuminates the interior lamps when an unlock signal is received from the remote anti-theft personality central security module. The illuminated entry feature will be canceled when any of the following conditions are met:
- 25 seconds have elapsed since the illuminated entry feature was activated and the interior lamp control is not activated (door ajar or courtesy lamp switch on).
- The GEM receives a request from the central security module (remote transmitter lock button pressed) and the interior lamp control is not activated.
- The ignition is in the RUN or START position and the interior lamp control is not activated.
The GEM will illuminate the interior lamps when any door is open or ajar. The interior lamps are; the dome lamp, the rear cargo lamp, the door courtesy lamp and the side rail lamps. The courtesy lamps will shut off when the doors are closed and the illuminated entry feature is not active or when the vehicle speed is greater than 5 mph (8 km/h). The interior lamps will not be reactivated until the vehicle speed is less than 3 mph (5 km/h) and a new door open warning lamp switch is received.
The GEM controls the interior lamps illuminated entry function by activating the interior lamp relay.
You have an electronic control module and relays involved in the operation of these lights also !
What
1999 Buick Lesabre 3800 how do I check for Intake Manifold coolant Leak?
the spark plug tips will look , LIKE A HORRORon the offender cylinder. there is one good sign and USA ? car, the OBD2 scans show the leaking cylinders are gross misfire DTC error P030x where tells witch cylinder is getting wet. (called misfire)the bank leaking OBD2 fuel trim way off the scale. radiator leak down test Fails. (a tool with same name) first off the gasket would have to be a double failure to leak to intake runners, water side to air side there are 2 parts, here the plastic top and aluminum main bottom intake manifold. evidence 2 if the gasket leaks below the HLA Lifter area gets wet . and the engine oil looks just like chocolate milk shake. nasty oil , MILKY for sure. if the wet ports fail water hits the pan too. also is not the upper plastic side, dry. and only bottom is coolant wet. see my threat vector photoas you can se , it be a double failure of the gasketif sucking oil see white smoke at tail pipe endor see steam from water (coolant burned) same place.
2004 jeep grand cherokee died on the freeway and now just cranks but won't start
Whew! Tight spot. Here are some quick and some more involved things to check. Hopefully, another responder will pitch in. A good time to call AAA.
Troubleshoot this issue step by step:
Check for Spark: Crank the engine and check if there's a spark at the spark plugs or ignition coil. If you have a spark, the crankshaft position sensor (CPS) is likely not the problem.
Fuel Pump Operation: When you turn the key to the "on" position (but not start), you should hear the fuel pump run for a couple of seconds. If you don't hear it, there might be an issue with the fuel pump or its relay.
ASD Relay: The Automatic Shutdown (ASD) relay controls power to essential components like the ignition coils. If the ASD relay is faulty, you won't get spark. Check and replace it if necessary.
Throttle Position Sensor (TPS) and Intake Air Temperature (IAT) Sensor: Ensure that these sensors are functioning correctly. They play a crucial role in engine performance.
Check the Key: If everything else checks out, consider the key itself. The chip in the key has a unique identifier code. Some replacement keys may mimic this code, so make sure your key is genuin..
Bus Line and SKIM Module: Verify the PCI bus line between the PCM/data link connector and the SKIM module. If there's an issue with communication, it could prevent the engine from starting
Sirius SU5 Kichen exhaust fan, does it have a fuse or overload sensor
The Sirius SU5 Kitchen exhaust fan does not have a fuse or overload sensor. However, there are a few things you can check if you're experiencing issues with the fan:
AIR System: The Sirius SU5 exhaust fan is part of the secondary air injection (AIR) system. When the AIR system is inactive, the closed AIR control/shut-off valve prevents air/exhaust flow in either direction. If you suspect an issue, you can find the AIR PUMP fuse (usually labeled as #64, 60 amps) in the under-hood fuse box. Try pulling the fuse to see if the fan stops running. Additionally, there are two relays related to the secondary AIR pump: the AIR injection (AIR) pump relay. Check if the relay contacts are stuck together.
Cooling Fans: If the fan is running continuously, it might be related to the cooling system. Check if the cooling fans are coming on as they should. Inspect the fuses and relays associated with the cooling fans.
Temperature Sensors: Ensure that the temperature sensors are functioning correctly. Faulty sensors can cause issues with fan operation. For example, codes like P0481 refer to coolant temperature fans circuit malfunction, which could be related to wiring, the fan itself, or the ECM.
2013 Cherry Tigo 2.0 TXE loose power when driving and come to a standstill. Engine cranked but does not start. What can be the problem
Try to diagnose the issue. That said, a professional mechanic with the diagnostic tools is likely needed.
Restart the Vehicle: First, shut off the engine, wait for about 10 seconds, and then restart the vehicle. Sometimes, this simple reboot can reset any signal errors that might be causing the "reduced engine power" warning light. It's still a good idea to have a mechanic check it out.
Since you've already changed the battery, it's essential to ensure that the new battery is functioning correctly. Check the battery connections, terminals, and cables. Also, inspect the electrical system for any loose or damaged wires.
Fuel System: Verify that there are no fuel-related issues. Ensure that the fuel pump is working correctly, and there are no clogs or leaks in the fuel lines.
Ignition System: The ignition system plays a crucial role in starting the engine. Check the spark plugs, ignition coils, and ignition control module. Faulty components in this system can prevent the engine from starting.
Air Trapped in Cooling System: As suggested in one of the solutions, make sure there's no air trapped in the cooling system. Bleeding the air out can help maintain proper engine temperature and prevent starting issues.
Remember that driving with the "reduced engine power" warning light on is not recommended.
Engine Malfunction, starter pulley jammed.
All questions in Cars and Trucks need 'year make model' please.But this could be a generator, chainsaw, leaf blower or mower in which case 'make model (what is is).On a vehicle, remove sparkplugs and try and turn the engine by hand using the big nut on the crankshaft pulley. Broken timing chain or belt and the piston is hitting the open valves. However, NO cars have a starter that has a belt, they are gear driven...
On my Fortress 2000 the turn signals not working every thing else works
this is no car it is Mobility scooter , right? electric scooter. tiny.
be does the hazard switch work right or not. test 1
test 2 all fuses good
now working means what?
all 4 or more turn lamps dead.? or stuck on, or some work or not?
only left or right or only front or rear fail?
this answer is for cars, posted to cars. and trucks.
test 3, remove all bulbs and test them 1 by 1, in the car. (lamps can in fact short out)
