    how do i fix my 4x4 in my 1989 ford ranger?

    Does low 4x4 work for sure? Do you hear the relays clicking under the dash when you select high range? Do the LED's light up on the switches?

How do I repair the four wheel drive on a 1999 Ford Ranger XLT?


It depends on what is wrong , is the 4x4 light flashing ? Are you aware of the complexity of the 4x4 system ? Has a electronic control module , has the ability to set an store DTC'S - diagnostic trouble codes !
Transfer Case The four wheel drive system is an electronic shift 4X4 system that allows the operator to choose between three different modes. The operator can switch 4X4 HIGH modes at any speed. To engage or disengage 4X4 LOW the vehicle speed must be less than 5 kph (3 mph), the brake depressed, and the transmission must be in NEUTRAL.
The shift motor sense plate, an integral part of the electronic shift motor, informs the generic electronic module (GEM) of the transfer case shift motor and contact plates A, B, C and D position.
The digital transmission range (TR) sensor is located on the LH side of the transmission, and informs the GEM when the transmission is in the NEUTRAL position.
The electronic shift motor is mounted externally at the rear of the transfer case. It drives a rotary cam which moves the mode fork and range fork within the transfer case between the 4X4 HIGH, 4X4 LOW and 2WD range positions.
When the GEM verifies the completion of the transfer case shift from 2WD to 4X4 HIGH (reading the contact plate positions), the GEM will then energize both pulse vacuum hublock (PVH) solenoids (supplying ground for 45 seconds). The PVH solenoid will allow a HIGH flow of intake manifold vacuum to the "wheel end hublocks", engaging the wheel end hubs to the front differential and transfer case to achieve four wheel drive.
Here are just a few DTC'S the system can set an store in the module !
P1804 4WD High Indicator Circuit Failure GEM GO to Pinpoint Test C . P1806 4WD High Indicator Short to Battery GEM GO to Pinpoint Test C . P1808 4WD Low Indicator Circuit Failure GEM GO to Pinpoint Test C . P1810 4WD Low Indicator Short to Power GEM GO to Pinpoint Test C . P1812 4WD Mode Select Switch Circuit Failure GEM GO to Pinpoint Test A . P1815 4WD Mode Select Switch Circuit Short to Ground GEM GO to Pinpoint Test A . P1820 Transfer Case CW Shift Relay Circuit - Failure GEM GO to Pinpoint Test A . P1822 Transfer Case CW Shift Relay Coil Short to Power GEM GO to Pinpoint Test A . P1824 4WD Electric Clutch Relay Circuit Failure GEM GO to Pinpoint Test A . P1826 4WD Low Clutch Relay Short to Power GEM GO to Pinpoint Test A . P1828 Transfer Case CCW Shift Relay Coil Circuit Failure GEM GO to Pinpoint Test A . P1830 Transfer Case CCW Shift Relay Coil Short to Battery GEM GO to Pinpoint Test A . P1838 Transfer Case Shift Motor Circuit Failure GEM GO to Pinpoint Test A . P1846 Transfer Case CONTACT PLATE "A" Circuit Failure GEM GO to Pinpoint Test A . Now are you sure you really want to mess with this ? You would need a factory diagnostic scan tool to check this out before you start replacing parts !

The low range light has come on its stuck on 4x4 and is slowing my truck down how do i fix this


you cannot run your truck normally in 4x4 low!!!! the low is designed to go slow slow.try shifting into neutral gear on column tap the high 4x4 then shift to reverse,back up 15feet then shift to drive.it should go into high 4x4 then if you want to go back to 2wheel high shift to neutral tap the 4x4 high until the light goes off,shift to reverse and back up 15feet then shift to drive and the 4wheel drive lights should all be off. then you'll be in 2x2 rear wheel drive. thank you for choosing fixya.com

I have never driver a 4 wheel drive. I am going from portland oregon to phoenix az. not sure how or when to switch to four wheel. does the truck need to be in park? etc.


Do you have manual locking hubs on the front? If you do, you have to turn them to 'lock' position. If you have automatic hubs, you skip that step. Never shift into 4x4 low range while moving. You must come to a complete stop to shift in or out of low range. Regular 4x4 (high range) can be engaged while you are moving. Let off the gas, and put it in 4x4 high range, do the same to go back to 2 wheel drive. Vehicles that are part time 4x4 (can be shifted in and out of 4x4) should never be driven in 4x4 while on a dry surface, as you can cause excessive wear or even failure of the system. So only use it in snow, off road, etc. Have a safe trip!

4x4 is stuck in low range with my 1989 Ford Ranger, the lights indicate that both 4x4 and low range are on, when I push the low range button to disengage then it flashes, however still remains in low...


The motor is what moves it. If you disconnect that, it will still be in low range. odds are that it is the motor, but removing it will not solve your problems. I would take it off, try to shift and then see if it moves. if not, replace it. if it does, its your transfer case.

Grinding in and out of 4 wheel drive


You say 'new' truck, 09? or new used? I have had 3 Fords, 3 w/ manual trans. case, if you go into 4x4 Low range, you must come to a complete stop before shifting the trans. case to 4x4 mode, and I always put trans (automatic) in neutral before slipping into 4x4, it engages smoothly, no grinding. 4x4 high range can be put in while moving, but I would let off the gas pedal, shift to 4x4 high range, then resume accelerating. If there is any grinding going on doing it as above, something isn't right. Check the trans. case fluid level also, to make sure that's not an issue.

1994 ford ranger 4.0 4x4 supercab


My wife just recently had a similar problem. She got stuck in the mud and put our 2004 F150 in 4x4 Low to get out. She didn't. Had to have AAA pull her out. She then left a bit later and the truck was still in 4x4 Low even after switching to 2WD. She even tried going backwards to get it to switch. So she called me frantically and I said I'd call her back. So I called our local Ford Repair shop and he gave me these instructions (loosely based on what the owner's manual says to do)

1. Start Vehicle
2. Switch to 4x4 Low
3. Put in Neutral
4. Switch to 4x4 High
5. Go in Reverse for a bit and then Forward a bit again
(You should now be in 4x4 High)
6. Put in Neutral
7. Switch to 2WD
You should now be good. If that didn't work, then try repeating step 5 after step 7.

Hope that helps, as it worked for us.

Can,t get truck out of 4x4 low range


try putting your truck in neutral and then shifting into 2 wheel drive shift on the fly does not apply to 4 low only 4 high and on electric shift models it wont shift unless your ****** is in neutral.
