As noted above, after working mostly this week, back to square one. Nothing working.
- checked fuses again - all good
- disconnected aux pump. No change.
- Checked resistance of temperature switch on side of tstat housing - no resistance (car warm)
- Tried grounding line to temperature switch. This results in clicking in KLIMA unit (just in front of fuse panel (on 85's only?)
The diagrams don't show the KLIMA unit, but presumably it must also have a relay that uses that temperature switch?
Anyway, moving on again to blower and maybe CCU and other stuff mentioned behind dash.
