Hey buddy, thanks for the response. Yeah in my relay box there is a green relay and the blue one which is the one blowing the fuses. Would you think its a defective relay? or defects causing it to blow out the fuse? since the fuse has blown 3 times, I'm just worried that the relay might be toast?? Is the blue relay for the low fan or high fan? Also another thing is, my car is starting to lose coolant and needs topping up around every 10 days. There's no leaks that I seem to see, and there's never coolant hanging around the engine or the ground. After a fast drive on the freeway for 10 minutes, and stopping at a drive thru....I can smell boiling coolant...like vapours. Do you think it might be linked to a defective relay?

Also, so I should chance the 15A fuse to a 25A on the blue relay?

Thanks bro
