It's above the battery with access to the mounting bolts gained by removal of the heater matrix air box.
Thanks for the help,. It's probably obvious when I look but is it the heater air box nearest the wing or the one nearest the engine?There is sufficient 'give' in the pipework to allow you to do this. The stepper motor is visible then. The fixings for the blower motor should be visible in the recess where the stepp and flap assembly is.

Thats good that is were i sent mine last fridayThere's no panel in there Toady, just the two rivets holding the motor in place on the other side of the ceiling of the battery bay.
The actual motor is acessible by taking the airbox & aircon box off. There is a letter box sized opening in there and you can see the stepper motor inside.
Sorry just re-read the thread and seen that you want the blower not the stepper motor. Not sure where that is.
To answer an earlier question, the Aircon box is closet the wing, the heater box next to the engine.

You need to remove main bonnet, wiper arms, 27mm nuts on wiper spindles + 2 self tappers, remove scuttle panel. From the wheel arch, remove battery box cover and battery (lower drivers window first !!) - the blower motor cover is a grp plate on the outside of the battery box, usually silicone and/or self tapper fixed - this needs to be removed also.
You now have both the "hot" side (nearest engine) and "cold" side (nearest inner wing) plenums exposed. These are both held down with self tappers to an ali plate. These are wrestled off the plate (usually siliconed down) and off the engine bay bulkhead. It may take a bit of leverage to break the mastic seal from both plenum covers - be fairly careful as the hot side contains heater matrix and the cold side has the air-con evaporator inside. There is sufficient 'give' in the heater hoses and the air-con hard line and hose to lift both plenums out of the way without having to drain coolant/drain refrigerant.
Once both plenums are off, the stepper motor and flap are visible. The blower motor is below the cold side plenum and IIRC is bolted to the ali plate mentioned above. Probably a 2 man job to undo bolts and drop the blower motor through the aperture in the battery box.
HOWEVER, before messing with all of the above.....it may be worth spraying the motor via the battery box opening with a good electrical restorative spray. The wiring to the motor is easily found in the void btwn the inner/outer wings, so you can put 12V on to the wires to check the motor's operation. The motor does tend to see road moisture thrown off the front wheels and it may be that it has partially seized. This is what happened to mine anyway!!
When re-assembling, make sure the large (75mm dia) silicon elbows are well seated on the stubs from the plenums and up to the flap valve housings on the underside of the dash roll top (get head in to pass side foot-well and look up) otherwise the 'blown' air just comes out in the general area of the pass. side foot-well.

Hi Nick, thanks for your reply, however I couldn't see any sign of a 'cover' in the battery area at all. There was no sign of anything to remove, it just all looked like a box shaped in the bodyshell for the battery to locate into. I'll try and get some pictures...
Hmmmm! OK, I've got an April '04 Tuscan Mk.1, but must have been one of the last Mk.1's to be built.My car had this 'hatch' in grp....and is as per Graham Varley's description of the blower motor removal/location in his Sagaris manual. I'd look closely at the battery enclosure/wheel arch for evidence of a silicone seal. The 'hatch' is pretty well wedged in there - sitting behind the Anderson plug and shaped to fit over the diagonal chassis tube at the rear of the battery tray, with 90 deg 'flanges' to lie against the pass. side foot-well/bulkhead and the top of the battery compartment. Of course, being TVR, yours may have had the opening glassed/resined over....but it would have been after the installation of the blower motor?
