Hi, My '04 3 Sportis doing the same - do you know which relay needs to be replaced?

It is going into the garage to see if they can work out what is wrong, so any info I can give them would be great.

Cheers

 

Stan7,

Any word on the exact relay that you had replaced? My 3 is headed to the shop for an oil change tomorrow and I would like to be able to suggest an exact part to have the fan fixed.

Thanks in advance.

 

I had this exact same problem that the fan not kicking in until upto 15-20 mins. I first replaced the main relay, but that did NOT fix the problem. Then later ordered and replaced the blower motor relay which made everything perfect. It was just a $15 part ordered by a call to the number in http://www.partswebsite.com/mazdapartsdealer/
