How come i dont get no heat?


The heater core may be plugged with rust. Good way to test it is with the engine warmed up put the controls in heat mode and then go under the hood and locate both water hoses going t the heater core. Hold on to both hoses to see if the temperature of both hoses are the same. If not, no water is getting into the core. . If the temp is the same, then control vacuum is not working. There is a check valve in the line to the control head that prevents vacuum fluctuations from moving the blend door when accelerating. Check it.

I have a 1997 jeep cherokee. In the morning, it starts just fine but as it gets warmer, it will stall and die and I have to put starter fluiud in the air intake to start up again. I have changed the fuel...


The age of your vehicle guarantee's a vacuum leak. It may sound silly but the truth is rubber grommets and hose's shrink and dry out over time and the harsh environment under the hood makes it worse. Check all vacuum lines and fittings attached to the intake manifold, valve covers(pcv valve), and be sure to check for a vacuum fitting on top of the intake just behind the throttle body. Does it fit tight in the hole? You can seal loose fittings with a high-temp RTV (Red) silicone sealant/adhesive. Several small leaks add up and your engine, heat/AC, will be all to glad to tell you about it.

A vacuum leak will cause exactly what you said your engine does.

Check under dash in duct system for any vacuum hoses blown off then check under the hood on the passenger side of engine compartent.If all hoses are connected then you will have to check the heater blend door actuator and the heater blend door lever for proper operation.

Heater air will only come out at windshield


your a/c controls in this vehicle are vacuum operated. you more than likely have a vacuum leak that can be under the hood or under the dash. take a look under the hood and inspect all of the vacuum hoses, mainly the small colored hard plastic hoses. if your car also runs poorly that means you may have a leak in your engine vacuum, check larger black vacuum hoses and rubber seal on brake booster that manifold vacuum hose goes to. if no leak found under hood check those colored hard plastic hoses. with any luck you'll have heat blowing throuh your vents in no time.

AC is blowing cold air, but it is coming out of the defrost and not the front vents. Why are the front vents not working?


Check over on the passenger side under the hood by the fire wall, there will be some elec. connection, just below that there will be a small vacum line that should go into your fire wall, check that it has vacum, it should also have a one way valve, small round looking some time that get clog, needs to have vacum that is what power the blend door's.

A/c blows at bilevel even though it is selected for upper vents


probably a vacuum hose. Check all over under the hood. Have it running and listen for a hiss while wiggling hoses around. I ran into the same problem a while back, and it was a cracked hose in about the middle of the intake. Be sure and check the hose to your vacuum pot, too. They are quite often mounted to the under side of the hood, and should ahve a vacuum line running to it.

May have a vacuum line leaking, engine light comes and said it was gas cap, replaced that and it still comes on. how many vacuum hoses are on my ram? Dodge Ram 2001 club cab magnum engine.


Many vacuum lines, but if it indicated a bad cap it should just diagnose the fuel vapor system. Your unit is 8 years old. Check the filler tube to see if the hose clamps rusted off. Being a bearer of bad tidings it could also mean the tank is rusted and has a hole in it. You can check the vapor cannister under the hood, your PVC valve, and vacuum hoses under the hood. Radiator shops can repair gas tanks and they should be able to pressure test your system on the vehicle without taking everything off.

Vents blow hot air all the time and heater/ac controls do nothing


I had the exact same problem with my '85 300ZX. Turned out to be a vacuum hose under the dash that had come loose. I noticed that others were brittle and would soon probably crack, so I replaced them all. There is some good info at http://www.thumper300zx.com/z31/vacuum/vacuum.htm

Check the vaccume line going into the firewall. Mine dry rotted and I had the same problem. I replaced the line and now it works fine.
