MK7 blower & A/C & Eperspacher diagrams - Relay missing?

[mortti]

Hello members. This is my first post here so thank you in advance for all support!

I'm having some problems with my MK7 transit blower system. I guess they are related somehow?

1) Blower not running at any speed setting. Fuse #55 40A checked and also confirmed +12V coming to fuse base. Blower connector disconnected and found no power or grounds in the pins.

2) Eberspacher working fine but blower not running so windows are frozen still after 1hr run. This fault was confirmed before #1 appeared.

3) I guess this van has partially deactivated A/C - one relay is missing and just wondering if it has something to do with this as A/C usually has something to do with moisture removal while selector pointing to windscreen symbol? Not sure.

I searched around the forum and found wiring diagram related to blower system but I would need one with A/C and eberspacher heating system. Any diagrams and assistance are much appreciated!

Points 1 and 2 were fixed by two new relays, can't tell you any details as I don't have any wiring diagrams. Point 3 just bad guessing and was related to previous. Selecting defog/demist? turns A/C on and blower to slowest speed as Eber does as well.

If anyone has wirind diagrams for aux heater (Eber) + blower + aircon I would like to check them out
