Used connector to bridge heat and AC

I "bridged" the heat and AC hoses until I replace the heat module in my Jeep and the connector (bridge) has broken twice this week. Thoughts?

Done so , far far from home, many times, hoses ruptured.
i think you meant the heater core hoses leaked
so I bypassed them with new hose.
some do this on warm tropical islands and run like that for ever
in fact , my first car a 1964 dodge, it was on option (heat)
there are exceptions, on some cars, as the hose feeds the thermostat base in this very odd way, (rice cars)
but not this car.

this the 4.0L ?

The lower speeds are controlled by a resistor block. That's what needs to be replace. It's usually located next to the blower. It will have electrical wires connected to it. High speed bypasses the block so it alway works.
If you want to replace it then;
) Disconnect the battery negative terminal if the vehicle have air bags. Wait 2 minutes for system to discharge.
) Remove the kick block on the passenger side. )Remve the glove box ) Remove the bolts holding the blower motor resistor. Push the red lock up and press down on the click ) Pull the block out. ) Install new block and reverse steps above.

As soon as the vehicle reaches around 180/195 (depends on the temp of the t-stat) the thermostat should open and thereby filling the top hose with warm/hot water.
Are you sure the thermostat is facing the right direction? Is the cooling system full?
Here is what you can do: remove the t-stat, replace any lost coolant/water and run the vehicle with heater on full blast for about 15 minutes or until the temp gauge is showing about halfway. During this time be sure to monitor the coolant level in the reservoir.
If you still have no hot air you may have a blockage or perhaps the heater hoses are not even connected.

Put an small brass butterfly valve in the heater line, on both sides. That will turn it off for the summer, and you can turn it on for winter. Alternatively, you could try and do like I'm doing on my '59 Chevy, when I get it out of the flood plain, and route ice water through the heater core.

I need to bypass my heater coil as my aircon is leaking 2003 kia pregio any photos?


Im not quite sure what bypassing heater coil has to do with aircon leak, unless you mean there's coolant leaking from under dash, if coolant is leaking, remove hoses at firewall and follow them back to engine, you can use one of them to bridge from one to the other. Or put a connector between the hoses

Window cable came off


I managed to get the cable back on the track but it took multiple tries and then to find out that the plastic bridge was broken ( the piece that connects to the window has a plastic connector(bridge) that holds the 2 cables one to bring the window up and one to bring the window down. well that connector was broken. To access that part you need to bring the window down so the "bridge' aligns with the hole in the track and you'll see where the two cables come together but it you can only see the bridge from the back. Maid really cheap by GM. Sorry I wasn't much help.

Car overheats while idleing fan not turning on ac not blowing


Check the Fan switch at the bottom of the radiator, if you disconnect it and have a power feed to the switch then it isn't a fuse.Bridge the terminals and if the fan comes on then the fault is probably the switch.

My rad fan isn't working and I'm leaking coolent like crazy from a hose right underneath the surge tank down near the control arm bushing how do I fix these problems?


replace hoses, fan issue is most likely a sensor (usually on radiator side) that controls on/off. If coolant is low it may not operate even if it is ok.
test by by-passing: 2 wire- bridge connections in connector
1 wire- ground contact

AC Fan Motor Goes Off and On


There is a wire connector repair kit available at your local dealer. You may also need to replace the resistor module due to the connector being melted in the cavity. The heat is a result of a loose connection (high resistance) that eventually melts the connector to the module. Hope this helps.

NO POWER TO AC COMP


Fuse #5 is for your ac.

On the Hi/Low pressure switch conection Terminal 1 and 2 are for AC clutch bridge them briefly to see if clutch engage if so system is low on refrigerent.

If you get cold air its more then likely Hi/Low switch is bad.

Note engine must be running and ac fan in on position.

1999 jeep cherokee do you have to remove the fuel pump to replace


The combination Fuel Filter/Fuel Pressure Regulator is located on the fuel pump module. The fuel pump module is located on top of fuel tank.

The filter/regulator may be removed without removing fuel pump module although fuel tank must be removed.

REMOVAL
  1. Remove fuel tank. Refer to Fuel Tank Removal/Installation.
  2. Clean area around filter/regulator.
  3. Disconnect fuel line at filter/regulator. Refer to Quick-Connect Fittings for procedures.
  4. Remove retainer clamp from top of filter/regulator. Clamp snaps to tabs on pump module. Discard old clamp.
  5. Pry filter/regulator from top of pump module with 2 screwdrivers. Unit is snapped into module
  6. Discard gasket below filter/regulator.
    1. Before discarding filter/regulator assembly, inspect assembly to verify that O-rings are intact. If the smallest of the two O-rings can not be found on bottom of filter/regulator, it may be necessary to remove it from the fuel inlet passage in fuel pump module.
    INSTALLATION
    1. Clean recessed area in pump module where filter/regulator is to be installed.
    2. Obtain new filter/regulator (two new O-rings should already be installed)
    3. Apply a small amount of clean engine oil to O-rings. Do not install O-rings separately into fuel pump module. They will be damaged when installing filter/regulator.
    4. Install new gasket to top of fuel pump module.
    5. Press new filter/regulator into top of pump module until it snaps into position (a positive click must be heard or felt).
    6. The arrow molded into top of fuel pump module should be pointed towards front of vehicle (12 O'clock position).
    7. Rotate filter/regulator until fuel supply tube (fitting) is pointed towards front of vehicle (12 O'clock position).
    8. Install new retainer clamp (clamp snaps over top of filter/regulator and locks to flanges on pump module).
    9. Connect fuel line at filter/regulator. Refer to Quick-Connect Fittings for procedures.
    10. Install fuel tank. Refer to Fuel Tank Removal/Installation.
WARNING: THE FUEL SYSTEM IS UNDER CONSTANT FUEL PRESSURE EVEN WITH THE ENGINE OFF. THIS PRESSURE MUST BE RELEASED BEFORE SERVICING FUEL TANK .

Two different procedures may be used to drain fuel tank (lowering tank or using DRB scan tool).

The quickest draining procedure involves lowering the fuel tank.

As an alternative procedure, the electric fuel pump may be activated allowing tank to be drained at fuel rail connection. Refer to DRB scan tool for fuel pump activation procedures. Before disconnecting fuel line at fuel rail, release fuel pressure. Refer to the Fuel System Pressure Release Procedure for procedures. Attach end of special test hose tool number 6541, 6539, 6631 or 6923 at fuel rail disconnection (tool number will depend on model and/or engine application). Position opposite end of this hose tool to an approved gasoline draining station. Activate fuel pump and drain tank until empty.

If electric fuel pump is not operating, tank must be lowered for fuel draining. Refer to following procedures.

FUEL TANK REMOVAL
  1. Disconnect negative battery cable at battery.
  2. Release fuel system pressure. Refer to the Fuel System Pressure Release.
  3. Raise and support vehicle.
  4. If Equipped: Remove fuel tank skid plate.

      2. Disconnect EVAP canister vent line near front of tank.
      3. Disconnect fuel pump module electrical connector (pigtail harness) near front of tank. Harness connector is clipped to body.
        1. Remove two fuel tank strap nuts. Position both tank support straps away from tank.
        2. Carefully lower right side of tank while feeding both fuel hoses through access hole in body. Fuel Tank Full And Not Drained Using DRB Scan Tool: To prevent fuel loss through hoses, keep left side of tank higher than right side while lowering. Do not allow hose openings to drop lower than top of tank.
        3. Continue lowering tank until clear of vehicle. Place tank on floor with left side (hose side) higher than right side
          1. Drain tank by removing fuel fill hose at tank. Fuel fill hose is largest of 2 hoses. Insert the drain hose (from an approved gasoline draining station) into hose opening. Drain tank until empty.
          2. If fuel pump module removal is necessary, refer to Fuel Pump Module Removal/installation for procedures.
          INSTALLATION
          1. If fuel pump module is being installed, refer to Fuel Pump Module Removal/installation for procedures.
