How to remove Heating/Defroster Control Knobs or a source for them

[DCTiger]

My Mk I does not have knobs and my MK IA does. I do not see how the plastic knobs are held (no allen key) on. Would it be easier to source a pair than to destroy the attached set? Did not see SS have them.

Also what is proper for MK I vice MK IA? Are they metal balls or are they plastic knobs?

TIA,
Rob

You'll find an opening on the bottom of the black plastic knobs. Insert a punch into the opening and push up and pull the knob to remove it. The early cars have a round knob held on by a screw.

Depends on the VIN.. the round corner cars have the metal balls, the cross body mki have the black knobs

My round cornered mk1 had push on plastic knobs

What was the VIN? Assume the car has the heater blower switch on the left of the steering wheel

My round corner car built in December 1964 has the controls with the black knobs.

If the switch is in the dash to the left of the steering wheel then it's probably a two speed fan unless the switch on the control for the single speed fan has gone bad. There was space on the dash for the switch to be installed which made for a much better repair of the single speed fan switch.

A good rule of thumb is cars with 2 speed fans have the plastic knobs, Have a MK1 Tiger in the shop right now in the 900's. (Dec '64) single speed fan, chrome ball knobs.

Single speed fan switch with chrome knob.

I am assuming balls vice knobs.
I have a single spd fan.

Anyone’s guess My Dec 1964 has 2 speed fan and plastic knobs. Totally original B9471379 Switch to the left of the steering wheel and marked with a removable aluminum tag with Blower on it

The round, chrome knob has female threads that fit onto the matching, threaded male lever. The end of the knob has a phillips 'cross' cut into it to make tightening and loosening the knob easier.

Sean, do you have a parts book handy? The cross over for the switches will be listed .. will show in Alpine SIV production numbers and that can be cross reference to tiger production timeline

The switch to the heater controls with the black plastic knob started with series 4 Alpine B94100001. The first B941 car was built 08/03/1964.
