heater blower speed

l would be cautious about putting in a larger fan, larger fan equals more work, which equals more amperage, which could lead to issues with the "marginally" sized electrical system we deal with.
I had a car that burnt up the resistor, when I had the fan out, I shot a little lube around the shaft on the bearing, spun much easier after that!

Hence, two resistor blocks for double the current capacity and a relay to supply more current ;-) I agree though. Ask me about my 12V's headlights that went our at 3am during a 25hr trek from Detroit to Denver. :hehe:

You go adding a larger fan and you'll pull more amperage through your system and who knows where that will lead. Hell, the connector that's on it now isn't even reliable enough for what it runs now.

I couldn't agree more.
