The spring should push the gears in, without the vac line on. The switch looks like it has a resistor between each contact so the readings are not a direct short. It also has the shift on the fly switch. I have the same problem. That was after many other spats with this dealership concerning my truck repair. If voltage switches, it's probably either your transfer case shift relays I had to look up where they are.
Or is it a manual transfer case? You may not even be engaging 4wd if there is an issue inside the transfer case. If the module sees something that doesn't make sense, it sets the light, and if the switch is bad, it just assumes you've never tried to command four wheel drive. I'm a bit too likely to start hitting things at random with a hammer, and I'm not exactly trying to exacerbate this issue. Just a side note, and sorry to hijack, but I can see the fuel filter along the frame rail there, when i had my truck in the shop non Ford dealership for repairs from my accident, i asked them to change the fuel filter while it was in there, the lady told me that the tech's said they didnt change the fuel filter because they would have to drop the tank. We recently posted a question as to suggestions on what may cause the problem, No answer yet. But all the same, I'd appreciate any help you can provide. It must have become stuck or rusted together? Sorry I am no help for you.
I had no way of knowing you'd know what you're talking about. Does anyone have any experience in replacing this themselves? Dealer didn't offer any suggestions, except to make an appointment on their 1 week wait list! The switch will just provide the ground when reverse is engaged. Pulled out of the parking lot, snowing, turned my selecter switch and again, no 4x4. I have been pulling my hair out over this same problem. I have been pulling my hair out over this same problem. The only way we can get it to come out of low is to disconnect the battery cable, Let it sit over night, Turn the switch off, Then reconnect the battery, It came out. Or is it a manual transfer case? Thi picture is from under cab right rear looking towards left front of truck.
Nothing at all seems to be happening with the top tube, and I can neither blow nor suck air through this. I had no way of knowing you'd know what you're talking about. The starting clutch engagement switch is located at the clutch pedal-2 seperate switches. Most likley a switch issue but at least this way you can be sure. By chance, does anyone have any pics of the underside of the truck, where this transfer case is located? It also has the shift on the fly switch.
However, most of these issues are bulbs blown or faulty switches. I expect it's probably a swich because you didn't mention a four wheel drive light flashing, which would be an indication of a module or output fault. Never used it again until I went skiing. On those trucks, you have to be in neutral, stopped, and with your foot on the brake to go into or out of 4X4 low. Could anyone clear me up. Could anyone clear me up.
I had an issue with a 97 ford exp stuck in 4wd low my friend tried all the basics ,neutral , braking etc etc. I'm sorry, I'm in a Ford Dealership and that's the most common problem I've found so far. Mar 08, 2014 Most vehicles have a low pressure switch that prevents the compressor from engaging so as to prevent damage to the compressor. First check for power at the back up light bulb connecter with reverse engaged may have power at all times when key is on. And, the vehicle is out of waranty. When it does not it could be corroded battery terminals. I get no grinding noises while driving, and after flipping the switch, I get no clunks and no lights.
It sticks out the back of the transfer case which is the aluminum looking thing. If this engages the starter check the neutral switch. Anyway, The battery cable was the only success we had in getting it out of low range. I might be totally wrong. I'm seeing a bunch of miscellaneous replacement parts, although most are listed for other vehicle models. We have had our 98 F150 do almost the same thing, Our problem is that it won't come out of low range after we put it in. There is a nuetral saftey switch on the auto-located on the manual valve arm the piece that the linkage from the shifter connects to at the trans.
Best of luck with it, let us know how it turns out. I'm not sure of your year, so I can't give you wire colors, but check for voltage switching from wire to wire when you switch the switch with it plugged in. I have a 1999 ford f250. Crawl up under the truck and hit the shift motor on the transfer case with a rubber mallet there known to stick if not used a lot. I would definately not rule out the swich because we've put a few in. Most the stuck in four by problems we see in the dealership could be solved with one tool.
