Ok, I thought I could get by since I have heated seats, but at 16 deg. during the day, I can't deal with it much longer. When I bought the jeep used, I checked AC and heat and both worked flawless. SO I drove it for a little while when one day, the heat was lagging badly. By the time I had driven it 30 min, it was finally hot. Then when the timing chain guides broke, I went through that mess with a fresh coolant flush and new coolant. Thermostat was good still. Very cruddy coolant and full of rust due to the spring rusting out on one of the rad hoses. PO claimed he replaced the Rad and water pump. Pump was in good shape. Did a complete flush and got a tone of crud out. Also did a revers flush on the heater core and got decent flow out of it. Deep cleaned the reservoir. The old coolant seemed very rich on water and was barely sticky when it poured over my hand. Engine ran and still does, in the norm zone. Now, the heat won't even blow no matter how long you run it. Since I also lost 1 and 2 fan speeds(strangely at the same time all the other stuff happened), It gave me some ideas. What happens is this: With the engine at running temp, I'll turn the heat on and, for 3 seconds, it will blow nice and hot, then fade to barely lukewarm, mostly cold. Turn it off, and back on, and the same happens. Also, when I turn it to the defective fan speed so the blower doesn't work, turn it back to a running setting, it does the same thing. After the flush, I've had this annoying rushing water sound coming from the dash. Never did that before. Never smell coolant when inside. Fixed all hose connections so no leaks there. Nothing coming from the condenser drain. have to top off the coolant every now and then. Sometimes, the coolant level goes down when hot, then when cold, returns to normal. Oil was changed when the flush was done. No coolant there. Blend door seems to work as it should. Big writeup, but at least Y'all know what I've got. LOL Little help??
