Electric Frunk Release Not Working

[Karl996]

Gentlemen

 

Car in question is a 2002 C2, Manual. Right Hand Drive if that matters.

 

For some time now the front hood can only be released by using the button on the key fob.

 

The switch on the side sill does not release at all. The switch for the engine compartment however works fine.

 

I'm not sure whether its the switch, the actuator release (but it works when using the key fob) or something else.

 

Would much appreciate some advice on how to go about trouble shooting this and changing the relevant part.

 

Thanks in advance

I keep seeing posts with the use of 'frunk' for the trunk in the front of the Porsche...the term is not a 'frunk', it is called a bonnet.

Karl: No expert here and the blueprint for this circuit is confusing to me, my guess would be the "frunk(bonnet)" switch in the side sill. Since the engine lid switch works and is fed by same power source I would think you would have power to the frunk(bonnet)" switch as well. Also since it is released by the fob that should qualify the wiring from the central alarm box as well as the actuator. Per the blueprint it shows a resistor and diode within the switch(!) so opportunity to fail is there. I guess it could also be wiring from switch to alarm box or the box itself, but I would start with switch first. Good thing for you is the fob works so you're not locked out! As far as change out, not sure. Bentley book says "remove drivers seat first(!). remove 3 plastic covers(shown inside of sill). loosen T30 Torx screws 6 turns, do not remove. lever cover up using plastic prying tool. Good Luck.

Most common problem like you have described is dirt and debris in the button mechanism.

Sometimes an air blowout will remedy without dis-assembly.

Likely because you stemmed from the British Isles at some point in time.

In N.A., bonnet = hood.

A hood in the case of a Porsche would be somewhat misleading since it is really a trunk, hence was born the genial term, frunk for front trunk, which in our NA view, would be pragmatically acceptable, no matter what a British ex-patriate would like to impose on us (US & Canada).

In Canadian parlance, ... We stand on guard for thee frunk!

Okay, you got me...

Back to the original posters question please.

Gentlemen

 

Thank you for the responses. I laughed reading the frunk, bonnet, hood comments. The interesting thing is despite the comments we all knew what I was referring to.

 

@ Loren - thank you as always. I'll give it a try when I get to the factory this afternoon.

 

@ Wildbilly - thanks for the info/thoughts. That will be next on the list if Loren's suggestion doesn't work.

 

Related question - does anyone have a part number for the resistor and/or switch ? I've searched but really cannot find anything.

 

Thanks in advance

Update - the blowing of air did not solve the problem so I guess there's n choice but to replace the switch and/or resistor.

 

Anyone no the part numbers for this ?

 

Thanks in advance

Karl: From the blueprint it appears that the resistor and blocking diode is internal to the switch. I will try to find an ordering reference for the switch. I am just guessing on the switch being faulty.

Karl: Found it on suncoastparts.com code# 9X6DSSWX Pick Front Trunk switch (frunk :)), of course.
