had GT2 decklid installed, new wire came with it from mashaw, but now the fan is spinning the wrong way( its blowing the air up and out) before the factory set up was pulling air into the decklid... anyone have an easy fix for this?

thanks

 

are you sure...all the decklid fans I've seen (including mine) remove hot air from the engine compartment but mine is a GT3 and not a turbo

 

Mine pushes air out as well - always has...

 

mine pulled air in and was a stock decklid.... a few other members noted after switching deck lid their fan blows out now also.. I just dont know if there is a right and wrong way

 

it is possible the new wiring has opposite polarity on the plugs and spins the motor the opposite way...only hooking it back up with your old wiring will tell for sure

 

The deck lip fan on all 996 Turbos is designed to pull ait through the deck lid, blow it over the engine, and exit below the engine compartment.

The Boxster is also designed the same way...air being pulled in through the right side intake by the engine compartment fan and then blown over the engine...exiting below the engine compartment.

Although Porsche may have had a complete turn around with the GT3, my guess is that in OEM form, the GT3 (and GT2) fan would also blow air over the engine.

 

no, you are quite incorrect about the GT3 anyway...my rear decklid is completely oem and has always blown air out of the engine compartment...and it is only used when the compartment gets hot...I usually only hear it at a track event when I come in after a session and shut off the motor the fan will come on and you can feel the hot air coming out of the top of the engine cover...

 

I got the Mashaw wiring on my decklid too, and it is pulling air out. i don't really recall whether it is pulling in or out for stock now.

 

Dock is correct for the TT...it is designed to pull air from the top and push it out the bottom. If yours does not work in this direction you could (likely will) throw codes eventually. Just reverse the polarity of the wiring should fix it.

 

+1 ...check out this thread https://www.6speedonline.com/forums/...flow-poll.html

 

just compared my new wire to the fan colors to my old (stock) wire... its a 2 wire feed and stock has a black wire on top with brown below it.. my new aftermarket wire has it with the brown on top black below it.. guess i just have to cut and spllce

 

I just got my bone stock 01 and it pulls air in from the deck lid into the engine, just another data point.

 

Cut and splice. I did that with my MA Shaw harness.

Works fine now. Before I did the splice, I got a warning message day 1 of the harness uncorrected saying something like the fan was failing....heat was too high in the engine bay. Once I fixed things, I have not had the message again.

To be clear:

stock decklid: air was pulled in, no issues
new lid w/ big wing from sambott,stock MA shaw harness (very high, OEM quality mind you)): air was blown out, warning messages
new lid, spliced harness wires: air is now pulled in, no issues

 

The fan should pull cold air from outside and push them into the engine... blow in... and my deck lid is stock.

 

Same here - it went off today and I checked. It sucked air into the engine bay. It's an '02 and OEM - never swapped out.
