Any time you do not have hot water in the hoses to the in side of the vehicle, your water has quit either due to you having only water in the system and it froze in the winter and you started it . or the propeller just broke of old age. make sure u dont have a check valve in the hoses going to the heater core in side the car. valve would be under the hood somewhere in the duration of one of the two hoses, which is the feed. this should do u good

Heatdoesn't work, A/C blows out warm air and defrosts blow out cold air


Right think the problem is the heater core is blocked with corrosion ,now remove the bottom hose from the rad and the heater hoses then flush every which way you can including through the heater core reversing direction then ,refit all the hoses fill with water only and see if heater works if so the remove the bottom hose again and drain ,then add a minium of 3 litres of antifreeze ,its a anti corrosion agent as well as antifreeze and without it the internal of the engine will corrode and the slurry will block the heater first then the radiator ,

No heat in 1996 grand cherokee


you could be low on antifreeze/water fluid or you have a blockage on your heater core.. I have a problem with my heater core being plugged.. Try disconnect the hoses to the heater core and see if water will flow through it or you can use air to blow through it.. Good luck

1999 Jeep wragler heater blowing cold air why?


Could be different problems.
The blower uses a resistor to regulate fan speed, the resistor could be faulty.
You would need to know if the radiator is full of coolant and if both heater hoses are getting hot. There may be a temp control valve in one heater hose that is not opening up to allow flow thru the heater core.

Heater runs but does not heat


If it is blowing air at different speeds inside the car, I think you are saying the blower works fine, but blows no heat.
If it is running different speeds but is not blowing inside the car, you probably have a plastic flap inside the heater assembly inside the car that is not opening, not allowing the air to come in.
That might likely be a vacuum issue, or maybe a mechanical one. (whatever is supposed to open the flap)

If the flap is working and you are getting different amounts of air inside the car according to the speed of the blower fan setting you have selected, go to the engine temperature.
Is the radiator getting hot?
Have you a temperature gauge to tell if the engine is hot?
If not, you will need to warm up the engine, and then determine if there is hot water in the radiator.
If you pull off the cap to see, it could blow up on your face, so you will need to find someone who can help you with this.
If the radiator is hot after about 10-15 minutes of the motor running, you are perhaps not getting hot water to the heater.
You would need to check the temperature control to see if it is working. This is often a mechanical switch located near the firewall of the Jeep under the hood. Usually it is the size of a small fist, and has a heater hose running into and out of it, and has a wire attached to the top.
It might have a wire to it that should move when you select hot or cold inside the jeep at the control panel. Sometimes the control wire will rust or break.. The heater hoses should be hot if the hot water is running through them.
If your radiator is low on coolant, often the heater inside the car will not work.

Jeep AC blows cold air at defrost and feet but not through vents


There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

I replaced the cluth and slave cylinder in my 1988 yj wrangler. After bolting everything to gether i found out that the shifter will not move out of neutral. some one please help.


Did u bleed the system to get rid of the air. Put fluid in the resovoir, open the bleed valve on the slave cylinder, put a hose on the bleeder valve and into a container with clean fluid and pump the clutch until no bubbles-close the valve and remove hose, check resovoir and top up--system is now bled.
