    I have an 89 ford bronco II and have no heat! after vehicle warms up, heat works but soon cools off. I have changed the thermostat, flushed system, backflushed the heater core, and serviced coolant. The floor on the passenger side does not get wet and the defroster does not cloud the window. Can the heater core still be the problem. The 89 bronco II does not have a heater control valve, so this isn't the problem. HELP!

If you have checked everything else, and your coolant system appears to be okay, try this.
Reverse the intake and outake hoses where they enter the firewall. All this does is reverse the flow through the heater core and will not harm the engine. Try it, it worked for me. Now I have more than enough heat. Let me know if this works for you.

Sounds like a bad heater core , your coolent may be low , check it out and add if needed . this will not fix your leak but you might get so heat untill you can check out the heater core

88 bronco II, heater hose going to water is cold, and my heater blows cold air, is my water pump going bad? the return heater hose is warm, it was heating once in awhile now it don't heat at all just cold...

I would try flushing heater core to see if it's plugged. I don't think it's waterpump, your rig would be overheating if it was. Leaking is most common waterpump failure.

Heat and A/C doesn't blow in an 88 Bronco II

The first thing to do is check the fuse. The fuse must be in the main fuse box. The position of the fuses is normally marked on the inside of the fuse box cover and also in the owner's handbook. If you don't come right with these, work your way through the fuses looking for a blown one. To ease your search the fan fuse it should be around 20 to 30 amps.

You could have an air bubble in the system. It is also possible that the heater core has debris blocking the flow of water. I would check to see that you are getting good circulation by checking the heater hoses near the firewall. If they are both getting hot then you may have an air baffle issue inside the heater box.

88 Bronco ii won't shift into 4 wheel drive.

Check to see if you are getting power through your switch on your dash. I also suspect your shift motor but it is a lot easier to check it with a test light.
