tall_tog Posted July 10, 2015 Share Posted July 10, 2015 noticed the other day my climate control had gone off completely. no heated rear screen no air con no fan couple of minutes later it all came back on did it again next day but took about 15 minutes before it came on today drove 50 miles with windows down and roof open to keep the hounds cool, pulled in to the street and it came on, turned the car off then back on and noting working again anything obvious to check/replace please?

stants Posted July 10, 2015 Share Posted July 10, 2015 Maybe a loose connection or dodgy fuse i'd start looking there Sent from my SM-G850F using Tapatalk Quote Link to comment Share on other sites More sharing options...
tall_tog Posted July 10, 2015 Author Share Posted July 10, 2015 fuses inside and under bonnet all look good, havent pulled the relay yet is that a possible cause or should i be looking at connections behind the panel? Quote Link to comment Share on other sites More sharing options...
stants Posted July 10, 2015 Share Posted July 10, 2015 Have you checked the other fuse box by your right knee ? Sent from my SM-G850F using Tapatalk Quote Link to comment Share on other sites More sharing options...
tall_tog Posted July 10, 2015 Author Share Posted July 10, 2015 yes , all good in there too Quote Link to comment Share on other sites More sharing options...
bitman Posted July 11, 2015 Share Posted July 11, 2015 a sticky relay might be the issue find the right relay, switch on the climate control, if not working knock on the relay to see if it clicks in. if helper as to switch it on / off so you can check (click sound) if the relay works Quote Link to comment Share on other sites More sharing options...
tall_tog Posted July 11, 2015 Author Share Posted July 11, 2015 took dash console out and checked they were connected fully to back of controls - all ok fuses are definitely all ok the relay for a/c is in the engine bay box and have removed and put back - still nothing when i turn the temp up to full or cold after a few seconds there's a click and the engine idle drops then it clicks again and engine picks up as if it trying but failing going to have to be an auto electrician job i think Quote Link to comment Share on other sites More sharing options...
Mr B Posted July 11, 2015 Share Posted July 11, 2015 Clicking you here is probably the elec-clutch on the compressor. if whole functions are dead it likely power supply/relay or the the console controls as being electronic they can play up as you describe & I have replaced a couple before due to full failure.

tall_tog Posted July 27, 2015 Author Share Posted July 27, 2015 quick update - auto electrician checked this over for me last week. took a while but in the end he reckons its the control panel as all the wiring checks out ok. is this likely to be the case? common fault? thanks Quote Link to comment Share on other sites More sharing options...
Mr B Posted July 27, 2015 Share Posted July 27, 2015 ^ does happen, I done a couple over the years, picked up used ones from breakers as they not a nice price from subaru stealers . Quote Link to comment Share on other sites More sharing options...
tall_tog Posted July 29, 2015 Author Share Posted July 29, 2015 thanks , fingers crossed a replacement control unit from eBay fixes the probelm when it arrives tomorrow, it better as away for a week in car ! Quote Link to comment Share on other sites More sharing options...
tall_tog Posted August 3, 2015 Author Share Posted August 3, 2015 final update for anyone else that experiences this issue the root of the problem is the circuit board behind the control dials. Straightforward unscrewing and unclipping the centre panel with vents and drink holder, disconnnect the plugs for hazard lights and the two plugs for heater controls, then four screws to remove the heater control box. finally little screws to remove the cover and get to the circuit board there are three little blue covers on this board and the fault with mine was that two of them had come loose allowing a tiny little very fragile circular circuit that fits over a small lug on each of the dials to come off and not be in contact with the main circuit board - hence no air con or fan After changing to a replacement control box a similar issue happened so today I've stripped it all down and put a small drop of superglue on each of these little covers to hold the circular things in place - be careful not to stick these too as they need to rotate! all is working again just fine hope this helps Quote Link to comment Share on other sites More sharing options...
