Poor Heat In My '97 Tj.

The cabin heat in my TJ is really poor. The temperatur is up there but there is no volume. It has A/C and I'm wondering if that has got something to do with it. Any ideas why this is?

Can you hear the fan and does it have the usual four different speeds?

Yes. The fan has all 4 speeds and it really works good. Was wondering if the A/C coil cuts down on the airflow. Am I wrong?

You said the temp is up there and the blower motor works good. Are you saying the air comin out of the vents isnt hot?

The air coming out is hot, but there is no volume. I don't believe that TJ's are lacking good heat. But before I start taking things apart.......

Your TJ has a couple mechanically/vacuum actuated flapper doors that block or duct the air to the floor, defroster, or dash vents. Someone is going to have to get in there and find out if a cable has come off or what's gone wrong. Now that we know the fan works and things are getting hot, it's impossible to say what exactly is wrong with those flapper doors... you're gonna have to get in there and have a look.

There is a couple of vacuum actuated flapper doors that might be causing the problem. Look up under the drivers side dash to the right and you should be able to see them. On mine the arm that attatches to the flapper broke off.

Re: Poor cabin heat....
Thanks guys. Ithink I know what you are talking about. I'll have a look at those doors. Could be a simple problem, hopefully.

This is off topic, but I also own a little taildragger 2-seater Merlin GT bushplane. I had heard of this mountainstrip upp in the foothills of the Rockies northwest of Calgary. Last summer I drove my TJ upp there to have a look at what shape the strip was in and if I could land there. This year I flew up there just to find the strip full of cows, of all things. I guess I'll take the TJ the next time.
