Bringing this thread back to life because I need to say thankyou.
My VS Calais had the climate control "fan amp problem" having the high speed only by selecting #3 manually.
It's been like this for about 4 years
yes I know but I kind of got used to the high fan speed. lol
After ringing holden for a price on a replacement unit and being qouted $165 I tried to locate a replacement from the wreckers......Boy that was a job on it's own. Only found one place on the other side of the city that had a possible?? working one and they wanted $75.
Then I came across this post. I rang G.B Telespares in Spencer street as quoted by DamoVS.
I asked them if they had a 2sd1297 Darlington transistor package and they said they have stock and they're $12.
So off I go grabbed one of these also bought a solder sucker as mine has gone walkabout.
Pulled out the fan speed amp, slowly pulled out the circuit board from one side to reveal the small phillips head screw that holds the transistor to the heat sink and removed the board and transistor. Grabbed the soldering iron and solder sucker, removed the old tranny got the new one out of the bag (which I noticed it was identical to the original "NEC D1297") soldered it in put some heat sink paste on the back of the tranny and secured it back into the heatsink. Put it back into the car, fired up the climate control and low and behold it's all working perfect again.
Total cost $12
Total saving $153
Now how cool is that? Felt good being able to fix it myself too!
I do recommend that you get a solder sucker but you can get it out without one but a bit more messing around. Also please remember to put some heat sink transfer paste on the new tranny.
I had some lying around, but there was probably enough on the original that I could have used.
Again thankyou DamoVS for pointing the way I really appreciate it.
Steve
