1997 Boxster Relay Diagram

[Geoff W]

Can somone post a diagram of the relay board and what each relay does? Thanks

[Loren]

We don't publish manuals here.

Why don't you tell us what your problem is and perhaps we can help?

[Geoff W]

well it seems the main relay is acting up, the car completely shut down at a light. The tow truck driver came and jumped the relay but its still acting funny.

[Loren]

Are you sure your battery is good? How old is the battery?

[Geoff W]

The battery is less than 18 months old, Im pretty sure its the relays, the car had some flood damage at one point. The AC relay has also acted up peroidically.

[Loren]

There are two banks of relays. One for the engine DME, AC compressor, start lock, secondary air pump, and the spoiler extend and retract in the rear trunk (behind the carpet). The other (for most of the relays) is up under the dash on the left side - above the fuse panel.

I have the relay charts posted on my website for MY 2000. It should be almost identical to the '97 relay setup, but may have different part numbers for the actual relay. I checked according to Loren's post and they all match on the rear relays he listed.
