Unfortunately I've had a few things come up and haven't had much time to look at the car.

From your post I'll assume that I have done something to the programmer when I took it out to cause the mixing door control to malfunction.

I'll send you a PM about the controls.

Well so much for the PM idea. My post count isn't high enough to be able to send PMs.

Hey Burg,

This just happened to me a few weeks ago. My core was half plugged and had to be replaced, and then I found this problem:

That arm is powered by a small electric motor inside the programmer. If your system is working correctly and everything is up to operating temprature, you can turn the temp control on the dash up and down and hear the little motor running and see the arm moving accordingly. The engine does not have to be running but the key has to be on.

I disassembled my programmer and found that the little motor was bad. I replaced it, reassembled it and it worked great.

I was going to take some pics of the repair but I did not. It is crazy that just a few weeks later I need them.



.

I will try to take the dash apart and test the motor when I can. I have been sick and busy the past few weeks so I haven't had much time to work on the car. Since it is stuck in the hot position and cold here it hasn't been much of a problem. Because the problem only started after I replaced the heater core I can only assume that I broke it while removing or replacing it.

Hopefully Monday night will give me the oportunity to pull it apart.

And since I can't PM, how much are you looking for for the control board?

Cheers,
Berg

I cant send PMs either due to lack of posts.

How about $25?

Well time for a long over due update.

Sorry FE3-1SD-R8A, I couldn't send PMs and a whole bunch of stuff came up that shifted my priorities. The lady and I moved into our first house, then there was some illness and time spent in hospitals.

Another problem cam up with the car in that the glove box got stuck shut. There are two buttons that need to be pressed to release the catch and one of them broke. I finally found time to get to the local wreckers and found a car just like mine, even the interior colour was the same. I pulled the heater controls and the HVAC manifold from that car. I also got the glove box door and a few things like window switches that were in better condition than mine.

Last night I finally got to dig into my car. I was able to get a small screwdriver into the glove box to push on the catch to release it. I then unclipped the latch and replaced it with the one from the wreckers. The glove box opens and closes again, but I can't lock it as my key doesn't match the lock. Not a big deal to me, nothing of value is ever kept in the car.

I then took everything apart to the point that I could access both the HVAC manifold and the control board. I turned on the car and tried adjusting the temperature. Nothing moved. I replaced the control board with the one from the wreckers and tested again. It had the exact same result. I left the "new" control installed in the hope that it will function better in the cold than the old one. I won't actually know for several months though as it only had troubles when the temperature is below zero, and winter seems to have finally lost its hold here.

I then removed the electrical connection from the HVAC manifold and plugged it into the new one. The motor moved! I had found the problem and started to remove the old one from the car.

Well I have determined that I am an unlucky guy. I had put the new HVAC manifold on the bench while I took the old one off and the cat knocked it onto the ground. The top mounting tab snapped off. Instead of mounting it with just two screws I took a little extra time and swapped all the guts to the other housing. I installed it in the car and it is working just fine.

I am still a little disappointed in the amount of air that moves through the vents and would like to try and find and tape up all the leaks, but I suspect that that might be a weekend long project, and with a new house I just don't have that kind of time.

And to prove that I'm unlucky: someone hit my car while it was parked in front of my house. Now I have to go back to the wreckers in the hopes that car is still there so I can get a new driver'* side mirror...

Cheers,
Kevin

I forgot to mention, I found the actual problem when I was swapping the guts over. The electrical connector plugs straight onto the circuit board. When I swapped the heater core out I must have been too rough with this connector as the circuit board was cracked, breaking a connection.

Well it'* been several weeks, and I would just like to say that everything is still working. On to the next project...

Cheers,
Berg
