Guys, I'm posting on this thread because I have a similar situation, but a few different facts, and was hoping to get some idea of whether failure of this part (or thermostat) is common. I was suffering the battery-drain issues, similar to others on this thread, but with an important symptom I don't think I've seen referenced. When I would connect a fully-charged battery, I'd get a very-faint crackle from just behind the engine - as if up under the cowl - sporadic, but pretty much any time the battery is connected. If left without driving, the car's battery will be dead in a few days. I did diagnostics tonight, pulling every under-hood circuit, starting with some solid contenders (radio, other stuff that makes a crackling sound), but ended up just systematically pulling fuses in a row until I reached (on my 2005 Roadster), Fuse 12 - Heated Washer Nozzles. I believe the crackling stopped - I've put the fuse back in (crackling), taken out (stopped) 3 times.

My question is - have others had a failure in this component - and is it more likely to be the thermostat I see referenced on a board (in this thread), or the heated nozzle itself? And - this was just this evening, so I'm leaving the battery connected tonight as a means of testing - and tomorrow or soon, I'll do the amp-test across the poles on that #12 fuse bay and see what the draw looks like. I think I'm on to the issue - but curious to hear what others may find in this set of facts. Thanks for a great forum.
