The doors for this vehicle are vacuum powered. you likely have a hose leaking allowing the door to creep open at low vacuum(idle) short term fix would be to run a hose directly to a vacuum souce to the actuatior on the top of the heater box.(get at it normally through the glove box)

I have a 96 jeep cherokee 4.0 sport. whenever i am driving steep grades at a constant 3500 rpm, i start blowing oil from somewhere. it dosent leak any other time. the rear main seal seems fine. what could...


At an Idle your 4.0 creates a vacuum between the throttle body and the intake valves. As you need more throttle less vacuum is created. The PCV ( positive crank case vent) works off this vacuum. At the back of the valve cover there is a vacuum line that goes to the intake manifold. This line can become clogged. An engine produces "blow by". If you were to take oil cap off you might see it at an idle. Check the air filter. there is a line from the valve cover that leads to the airbox. this is where the "blow by" goes when pcv line is clogged. Part 1 the problem...... part 2 the fix.

Have you checked the coolant level? What you describe is exactly what happens if the coolant level is low. When stopped at idle, hot coolant is not circulating through the heater core, so no heat. As the engine increases in rpm's when you pull away from the light, the water pump is spinning quicker, and some coolant is making it to the heater core. So check the level, and if it is low, keep an eye on it to see if it drops again. That of course indicates a leak somewhere. Get it fixed, as overheating the engine leads to costly repairs and worse case a new engine. Let me know how you make out with this.

Heat blows cold when car is idling


You have an air pocket in the cooling system. To bled it out you will have to park vehicle on an incline or jack up the front end untill the radiator cap is higher than the heater core. The remove radiator cap and run engine until warm then hold rpm to about 1200 rpm's and top off coolant level until you have no more bubbles.

Heater blows cold air when idle


Sounds like you may have a partially plugged heater core. You could flush this out separately, from flushing radiator & engine block. Diconnect heater hoses going to your heater core and clamp off, so not to loose coolant from engine. Now hook up separate hose to one side of heater core pipe and flush out with typical garden hose. Repeat procedure on both heater core inlets. Reconnect original heater hoses and test difference. You may have to add an additional litre of antifreeze. If this don't work i suggest changing heater core. Good luck.........Ron.
