While I am out working on the various issues that the 5KTQ has today, here is another one. For some reason, I no longer have a blower. I have tried setting the temp to the highest setting and using both hi and lo fan control as well as setting it to the lowest setting and doing the same.

Now, it DID come on the other day, for about 5 mintues, then shut down again. Prior to that, it went for about a week where it would run high and low intermittantly, about 1 second each... so it would blow hi for 1 second then low for 1 second and then cycle like that until I got annoyed and just turned the climate control off.

It did that in every setting, from econ to defrost and then just stopped working all together. I had given up on that but then it came back on the other morning at full blast for about 5 mintues, and promptly shut itself off.

Right now, I am thinking that either the motor is going bad and I need to replace the blower motor, or there is a bad temp sensor telling the CC unit incorrect temps causing this problem. I am leaning more to the temp sensor thing at the moment, but wanted to ask for suggestions...

I do have the bently book and am going to go through that routine in just a bit after I get the door back together after tearing it apart in my previous post.

Cheers
Jeff

Sounds like motor brushes are worn to nubs. Search this forum.
