  • David Feb 16, 2012

    when i saw the broken cable i rubbed them together for good contact put a peice of tape on them and started my trucl and the idle was almost 2000 rpms and motor was shaking so i shut it off and havent messed with it so basicaally is it possible for that or just happend at the same time

  • David Feb 16, 2012

    thank you that is helpful for replacing it but i can still start and when i hooked it up truck started knocking and extremly rough idle actually normal cold start is 1300 rpm and now it was up to 2000 rpms of course it lowers once warmed up

    my best guess is sensors are working that werent before but could that effect timing? the truck timing was advanced already but nothing like now so is leaving it unhooked going to hurt anything?

I suggest you make a replacement using a good quality heavy duty cable if it is the cause of your problem it should rectify itself quickly after figment. Try to copy the original as closely as possible, and after figment give the ends a coating of vaseline

SOURCE: cant find heater core hose

They are two hoses that go from motor water pump, they are 3/4 size or a little more, they go in to body fire wall, you can disconnect both and join them by pass with pipe and two clamps You will recognize them easy, they are smaller than radiator hoses

The easy way to verify a bad heater core is by using the heater or defroster if the vehicle has antifreeze in it. If it only has water in it when the defrosters are on you will get a steam build up on the window like its getting fogged up. If antifreeze is in the system when the defroster or heater is on the air coming out will have an odor that smells sweet.

2004 Ford F150 passenger tail light grounding point?


First look under truck for ground straps that go from frame to bed to see if one rotted or fell off. Bed usually has at least one ground strap. What is weird is that if no ground at all neither side would work. If light socket has 3 wires coming to it then ground could also be coming in through harness from far away. Yours is odd because usually ground is same for both sides. If you have no other choice find the two wires with power (you said you did this already) and cut the third (ground) and put a crimp on wire eye that you can then screw to body with sheet metal screw. Before you do that take bulb out and look for spot in bulb socket that is ground point and see if corroded or broken off. You may need new bulb socket.

The air is warm coming out of the passenger side vents and cool out of the driver side vents,But the temperature button won't increase the temperature. Seems stuck on Max Cold


it's dead, jim. time for a troubleshoot and repair. These toyotas are notorious for climate control problems. Either your control panel is broken, or the electronic air blend motor is broken, or some plastic in between. 25315509-zejmo41uy3tce5x43qikgza0-5-0.gif

I need to replace the heat core in my blazer... how do i do this?


Draining the Cooling System
  • Park the vehicle on a level surface. If the engine has been running allow it to cool completely.
  • Drain the cooling system. Remove the radiator cap from the radiator. Locate the petcock valve on the lower corner of the radiator. Place a waste oil collection pan underneath the petcock valve and turn it counterclockwise to open. Allow the cooling system to drain completely.
  • Label and remove the heater hoses from the heater core. The heater hoses will connect to the heater core in the engine bay, on the firewall, on the passenger side of the vehicle. Use either the Phillips or the flat-blade screwdriver to loosen the hose clamps that secure the hoses to the heater core. Then pull the hoses off the heater core.
Removing the Heater Core
  • Remove the heater core cover. Move to inside the passenger compartment. Locate the heater case. It will be bolted to the firewall, below the dash on the passenger side of the vehicle. Use an appropriate sized socket or wrench to remove the five screws that connect the heater core cover to the heater case, and remove the cover.
  • Remove the steel straps that secure the heater core to the heater case. Unscrew the four screws that connect the steel straps to the heater case using a socket or wrench and remove the straps.
  • Remove the heater core by pulling it out of the heater case.
Installing the Heater Core
  • Place the new heater core into position inside the heater case. Be sure to carefully guide the inlet and outlet tubes through the holes in the firewall.
  • Reinstall the heater core retaining straps, by reinstalling the four screws that secure them.
  • Place the heater core cover into position over the heater case and reinstall the five screws that secure it.

Refilling the Cooling System
  • Reconnect the heater hoses to the heater core. Slide the hoses onto the inlet and outlet fittings that extend through the firewall, and tighten the hose clamps.
  • Close the petcock valve on the lower corner of the radiator by turning it clockwise.
  • Refill the radiator with a 50/50 mix of antifreeze and water.
  • Reinstall the radiator cap onto the radiator.
  • Run the engine and visually inspect for leaks.
Good luck and take your time, keep me posted and don't forget to rate please.

I am needing advise on the heater core for my 95 grand am. it is leaking on the floor board passenger side pretty badly (front and back) . Is this something a stop leak would be worth trying until the...


Don't use stop leak, use regular kitchen black pepper. About 2 tea spoon should stop the leak soon as the pepper makes it way to where the leak is. Black pepper will clean up after you flush the coolant system and will not leave any residue like the stop leak that will restrict the coolant journals and water jackets in the engine block and radiator.

Removed the center console to get to the panel that holds the heater core. the heater core is in the center of the car under the radio. There are 7 screws holding the cover on. Once you remove the 7 screws, there are two straps that hold the core inthe heater box (2 screws per strap. Some cars are easier to get the heater hoses from underneath after jacking up the car, some you can get to from up top under the hood behind the engine. It's not a 15 minute job, but not difficult at all. I usually suggest pulling out the passenger side seat to give a comfy place to lay while doing it. the seat comes out with only four bolts, and you won't have to contort your self to get the heater core out. Your low coolant light is due to air trapped in the system. Anytime you open the cooling system on a 3.1, you have to bleed the air out using the bleed valves on the t-stat housing and transfer tube (some only have one on the t-stat housing. If you have a 5 speed, your going to remove the shifter knob and just yank on the plastic that had the boot. (it only has snaps that hold it on) Then there are 2 bolt holes in the armrest compartment. and 4 more which are under the boot and plastic. Very easy to take off and put on.

Good luck, and other way is to by pass the heater core at the heart hose, but your not going to have any heat.

01 jeep grand cherokee heater works on driver side blows cold on passenger side


You have 2 posibilities.there are 2 motors on the heater box that run the blend doors for each side.That side motor may be bad or worst case the blend door arm that connects to the motor is broken.If it is broken the whole dash has to be removed so the heater box can be taken out to replace the blend doors.Big job,do a heater core while your there if you fix it so you dont have to do it again.
