I have my dash and console out and need to open my headlights but my manual knob isn't working. I push the knob in to turn but it doesn't engage anything. My headlights work perfectly so have never tried to use the manual override, I thought I read somewhere that they only work with power to the headlight switch (which seems counterintuitive) but searched and couldn't find again... is that true? I noticed what look like pliers marks on the bar so thinking the PO had the same issue.

You really have to shove the knob into the fender hard to get it to engage.

If your plastic gear was cracked, once you got the knob engaged, you shouldn’t be able to turn it.  Since your lights work fine, I am assuming there is nothing wrong with the mechanism.

The whole motor assembly/plate can be removed without pulling the radiator, but it’s a bitch, due to the limited access. There are three 10mm bolts (IIRC) that hold the motor plate to the drivers side fender.

My gear broke, so I had to replace it.  It probably took 2-3 hours to get that assembly out, so you will want to avoid it if you can.

You can practice with one of your windows and your hand crank...  the mechanism is basically the same.

Maybe (probably) I'm doing something wrong here... but I'm trying to reach around to the bottom right of the photo hereIMG_1154but I can't reach two bolts which are to the right of the small gear in this photo with a ratchet without hitting the radiator IMG_1155and a photo from above of the two bolts I’m talking about...F32A32D0-3015-4CD2-9547-E05CC8FE04CC

I had to use a short open end wrench, and could only turn each bolt about 1/8 of a turn (or less).  I eventually got that plate out without removing the radiator or the headlight bucket, but it was a P-I-A.

It can be done.

I think I may have also disconnected/removed the limit switches for a little better access.

also the micro switch what is on top must be disassembled .

But when you dont have this done before whit the radiator  still in place it's better and easier to take out the radiator first.

also easier to adjust the engine mount plate on the gear, and the micro switches 

Simon

taking off the fronthood makes it more easier to take out the radiator  .

this is a 2 man/wife job.

have you a carlift ?

whit the front lifted up before taking the radiator out makes the bleeding easier after replacing the radiator. And keep the pressure cap on the pressure tank.

You are sure that one of the 2 switches not is broken ?

hard to see on the pic's but the one what showed the underside of this looks not fresh.

That the manual knob not works as must be , will not say that the other part of the system is broken. Dont ask how I know this.

As Rocky mentioned , try first connect the 2 leads from the motor to a battery  before do something else . To be sure the switches are OK .

 

easiest from under the car.

I Always following those steps to check the gear.

check the switch , whit lights on , what not is pressed in by connect the 2 leads to eachother ,

thats the switch besides the radiator on top.

when you pull off one of the leads from this switch maybe you can see that the motor will turn but  stuck .

sometimes the motor will warm up a little , there is a safety thermic switch mounted on what gives a ,,click" when the motor stuck (clicks off and on ).

Or check the motor how Rocky explain , when the plastic gear is broken , the motor will turns a little .

take off the hood and  take the radiator out .

When you know how the system works and how to adjust probleby the next time ( other Pantera ) you can fix it whit out taking the radiator out .

But from the underside.
