Can anyone confirm the location of the heating/AC blower motors relay and fuse location for a 79 Shadow? On my LHD 79, I see a round plastic disc with 2 wires on top of it's cover just under the passenger blower motor. Is this the fuse for the blower motors? There are also a few relays above it? Is the first one the blower motor relay? HELP! Richard | ||

There is a fan speed module located dash center by the ACU. Chapter M in TSD4200 shows location of relays and other electrics. Fuse chart is on the fuse panel itself. This module is inside the car. | ||

From SRH33576, after my having replaced the original Lucas relays with Bosch-type equivalents:  Brian | ||

Also, for far more about the scintilla switch, see the topic, What is this? OR It's Hell Getting Old(er) and 1978 Shadow Choke/Starting Problems Brian | ||

By the way, yet another topic started by Mr. Greene, that based upon the title should have no pertinence here, but it does: Petrol Gas Flap PROBLEM (1975 Shadow RHD). See the document on the Fuse Box first, as it directly pertains to the Climate Control system, then see the other PDF to see how it can link in to the fuel filler door. (I think all this is SY2 series only if my filing system is accurate). Brian | ||

We recently bought a '77 Silver Wraith II, which has several electrical issues (A/C and Heater doesn't work, nor does the blower motors, the radio and antenna, radio (not factory), as well as others. Right now, I'd be happy locating and checking out fuses and relays, and perhaps, the wiring for these items. How easy is it to access the fuse box and relay array? I'm 68, and have limited range of motion with my back. Please advise Thanks! VIN is LRH31728 (Message approved by david_gore) | ||

Michael, The fuse box is (in my opinion) easy to access as it's under the knee roll on the passenger side and once you drop that door open, there it is. Relays are another story, as they're spread about the engine bay. Here is an image of three of the major relays related to the AC system that are affixed to the firewall and hide beneath the air circulation conduit.  | ||

Here's a link to an annotated version of the fuse board diagram I made: SY 2 Series Fuse Board | ||

Shadow 11 SRH 38326, I have no interor fans,also no compressor engagement,air distribution seems to work and the control flaps direct air when the facia/auto switch is moved.. I have looked at the relays under the bonnet RHD drivers side and as you look at the relays from the front,the left side relay is cooked. I have a 12v feed via the yellow cable to the centre of cooked the relay. cooked relay now changed and still no interior fans.any suggestions, thanks (Message approved by david_gore) | ||

Near that relay you should find a small rectangular box with a screw fitting in the centre of the lid. Under that lid you should find 2 fuses (one is a spare/ replacement fuse). The fuse supplies the fan motors and the fuel filler flap opening solenoid. |
