As its coming into summer here in Queensland I thought I take a look at why my Auto Heat stopped working. Bit of a back story first, when driving the car back to Brisbane after the purchase it was getting a bit cold so i yanked on the red lever next to the park brake hoping for some warmth... something went snap and the lever would not stay up? DOH! just realised what I did was probably not good @#$$#^%^%$.
Anyway as this was not high on the "Things to fix list" i left it and got on with all the other stuff. Now before i tackled the problem I got on here and... well theres a lot of posts on this subject and it was all a bit too high level for my skill set. So I started with the basics.
1. Did the rear engine blower work? - yes but it seemed to be on or off and full blast was on.
2. Could i hear the motor in the Auto heat unit when i turned the control knob - Yes!
3. When i took the inspection cover off was the rod disconnected - Yes.
This is simple I though, just pop the rod back on and Roberts your fathers brother as the say.... well the rod was not going back on via the inspection hole in the side so i undid the 4 screws that hold the AutoHeat console/unit to the car, popped the rod back on, turned the knob to test and.........well that was the last time it showed any life? the motor went to fully closed or open (can't remember now) the fan would not work (unless I connected the 2 yellow wires together) strange i thought... must have blown a fuse..... nope fuses ok and power coming to the unit? It was at this point my electrical knowledge ran out, so as many other before me have probably done, i put it back together and added it to the bottom of the "Things to Fix List".
There are quite a few things well before this but as I had to take the unit off to access the handbrake cables, i thought I would have a wee look see....nothing miraculous had happened and my elecrical knowledge has not increased, so i didi the next best thing... took it apart and took loads of pic to post here and somebody will just give me the answer
Seriously, I did notice something on the circuit board that maybe a clue to the fault. one of the little transistor thingys (if it's not a transistor it ok to tell me) looked a bit frazzled?
Could the be the problem? please have a look and any suggestions or offers to fly to Australia (or drive to Brisbane if you are already here) and fix it for me would be welcomed
Here is the pics:
This what i think it should look like?
Honestly, any suggestions welcome...
To be continued....
