I could use some help also.Interior fan is slow so I changed the relay.JAE was out of stock so I got a Bosh 20/30 amp that fits. Fan ran well, but after 5min of warm up to change the oil, smoke was coming from front air intake. Turned off fan and pulled relay.Fan still runs slow even with relay out.Any idea's?.Hope I post this correctly.

have you got a multimeter handy? i'd need you to check the current loads before i can help.

good.

#1 how much current is the fan drawing? does this fluctuate at all?

[Evil_Dr_Fish]

I readily admit I'm not experienced with Auto Electrics, so I'm mostly putting this idea out there for those who are...

The fact that it still runs even with the relay REMOVED makes me think you've may have some kind of short circuit going on?

As a thought - does it still run even with the relevant fuse removed?

[WayneB]

The fact you had smoke billowing from the plenum is not good.

Something has shorted in there

You had better get in there and have a look at the damage.

[Guest teigan]

if it was an electrical fire, where did it originate? wayne's right about pulling the plenum cover. not sure if the electrics are related, but i'd be worried enough to look inside.

Errr Im sure they said the smoke was coming from the front air intake (ie NOT plenum)

I took that to mean either it was coming up through the air vents or from the rad areas? The former would make utter sense if the motor was about to go phutt... the latter ...errr MAYBE if its the rad-fans that it's all cross wired with?!

Smoke came from the air intakes in front lid at base of windshield. The plastic cover for the motor was of course quite hot.Have not turned the fans on since. Great day here so drove the Turbo to work and to clients.Still have my ignition miss per other post also ,but had fun today.Going to LOG Fri and will be back Tue. to again work on car. Thank's for help. I'll try and get a multimeter reading tommorow before leaving.

Still preping for LOG even though i'm Flying out . All is well. Removed plenum and fan to find one motor seized. Lots of wd-40 and they where fine till more smoke. Pulled the relay to find one of the terminal spades pushed out of the relay box.Pushed it back and all was well. Air blowing cold and fast on way home.

Thank's for the help.
