Question about 2008 Jeep Patriot Sport

1 Answer

My son borrowed my 08 jeep patriot during a snow storm. He put it in 4wd to get out of someones driveway. (I was not with him,so I'm only going by what he told me) Anyway after getting out of the snowy driveway he said he tried to turn off the 4wd but everytime he shut off the jeep and started it back up the 4wd! light would come on & stay on. I took it to a local mechanic who reset it and then updated the system or something like that. Still the light came back on. After the reprogramming it seem's like each day a new problem occurs. One day after having the work done I drove it for about half n hour. When I restarted it I got 3 beeps from the dash with the airbag icon light coming on for a few seconds, then it goes out. It is still doing that. Next day out with the jeep I noticed that my heat does not blow on the floor setting anymore. When its set to 'floor' it blows out the top/windshield area. I have not driven it since so I don't know what will be next to go. To rap it up I have 4wd! on at all times, air bag warning beeps and light for 3 beeps upon starting, and the heat is not working properly. What is going on? I am disabled with very low income, no savings and no warranty.

The irregularity of the errors suggest a CPU program problem.( corrupted) I would try resetting the CPU using a code reader. ( Local auto spares shop do it for free)Check that the battery posts and terminals are shiny clean and tight

Don't mess with it!!!!! Your new vehicle has a warranty. Get back to the dealer ASAP and don't take anything apart. You paid good money .... let them tear their hair out.....that's what they get paid for!!!!

SOURCE: 2004 Jeep Grand Cherokee Heater will not turn off

It could also be the rheostat that controls it. it's on the fan plenum under the dash. inserts into the plastic plenun.

SOURCE: 98 cherokee starts for 2 seconds and shuts off.

Sounds like a serious short and or blown fuse. Check battery voltage. Move on to underhood fuse block. Check all fuses. Move on to cabin fuse block. Check all fuses. Check fuel cut-off switch. Reset switch. If you still have the problem and the battery is good than you have a short in your starter, alternator , or fuel pump. I won't go into lighting cause I figure you can tell a bad bulb from a good one. If your battery voltage is 12v + with the engine off your ok. If you can start the engine, check the voltage at the battery again, it should now be around 14v. If not , go to the positive terminal on your alternator and check the voltage there. If you read 14+ at the alternator and not at the battery , then the wiring in that circuit needs to be changed. A quick alternator test is to disconnect the negative terminal of your battery while the engine is running. If the car dies then your alt is bad. If you read lower than 12v on your battery. disconnect it, add water unless its maintenance free., charge it on a charger or preferably get a new one. Go and feel your starter for excessive heat. A short will also heat up your negative battery terminal

SOURCE: I'm having an issue that seems to only occur 50%

I'm likely to forget a few but generally there is one from the battery to the fender nearest to it, one strap from the engine to the firewall and usually at least two near the computer. generally they are smaller wires with a star washer attached to the fender etc, the engine/firewall strap is generally a woven exposed metal strap. connected between the back of the engine and firewall.Only one that isn't obvious would be under dash. i generally run a wire to the dash frame right from the battery and don't even bother looking for the real ground points.(I actually run a 10gauge or heavier wire all the way around and connect everything to it on all my vehicles, then, never need to worry about it again.) I can't say for sure if this will fix the problem but it will eliminate another variable from the mix.

SOURCE: Why would my 2002 Jeep Grand Cherokee only blow

Sounds like you need a blower motor resistor located down under dash on pass side next to blower motor. This is a comon problem and I have changed many of them. thats just the fan speed problem. Ive seen the blend doors break easily on those jeeps. thats inside the heaer core box and moves the flap from hot air to cold air. If it is stuck halfway -or mostly to cold- you may only get luke warm air. If they had the heater core out-maybe they possibly broke it.

You need to connect a code reader to the vehicle and check the PCM for trouble codes. This is the first area that must be checked, otherwise, it gets real expensive when you start to guess on part replacement.

This truck plows a .3 mile long driveway with a big hill. the clutch is fairly new but got very hot and smelled bad during the last snow storm. I wads told to check the transmission fluid and fluid in the...

The resivior for the clutch is under the hood on the driver's side outside the Brake master cylinder. You should be able to look through the plastic housing to read the fluid level [ between the lines ]. If it needs fluid, it takes DOT 3 brake fluid, be careful to wipe any dirt or gunk off the cover before removing it. The fluid has to be checked from under the truck by removeing the plug on the side of the transmission, the level should be just under the opening. The type of fluid depends on the transmission that's in the truck [ an autoparts store should be able to help you with that ].
These fluid levels should not affect the clutch as far as slipping, oil or grease leaking onto the clutch will or a weak pressure plate will cause it. Plowing in to high of a gear also will put tremendous strain on the clutch, I would recommend plowing in the lowest gear practical, if 4wd. put the transfer case into 4wd lo range- you can always use the transmission gears to go faster.
