Editing Resistor pack (section)

== DIY Replacement via service panel (non a/c only) ==

'''1. Remove obstructions above heater unit'''

Remove front access panels, radiator shroud panels and washer bottle.  You '''might''' need to remove the heater pipes and jubilee clips as circled, though try it and see if they're in the way.  There is one pipe each side and a bit of coolant will come out, not a lot.  Make sure car isn't running!

As viewed from passenger side front wheel, detach white plug to heater flap, unscrew and remove the aluminium retaining bracket and unclip heater from blower.

'''2. Separate fan blower from heater unit'''

Pull the fan blower (near passenger side wheel) away from the heater. Stand up heater in the well so the hole is facing up. Very fiddley. Its at this point you'll discover whether disconnecting the heater pipes will give you some more room. You might also find that the wiring behind the radiator is also getting in the way - cut the two cable ties that hold it in place and then re-attach later.

'''3. Rotate fan blower unit'''

Heater now standing up (at top). Rotate blower (at bottom) around so that the resistor pack is facing up. Rotate towards the nearside front wheel (its further to rotate but theres less for it to foul on). Again, very fiddley

'''4. Replace resister pack'''

Resistor pack is attached with two screws (one you cant get at without removing the wiring). You might need to cut the wiring from the existing mass of molten/corroded connectors and attach new red female crimps. You might be able to salvage the existing shrouded female crimps if you simply cut/snap off the entire male connector from the old resistor pack, soak the crimp in plusgas/wd40 and then extract the remains of the male connector with snipe nose pliers. Once replaced rewire as shown. For additional peace of mind, consider a liberal application of grease over the connectors to prevent/delay future corrosion. Additionally, consider drilling 2 x 6mm holes in the bottom of the tub (1 at front, 1 at back, 6cm from either edge) beneath the blower to provide some drainage (as per lotus service bulletin).
