tonycj 0 Posted December 3, 2008 Getting up on these cold mornings my heater blower is on for most of my 15 mile drive to work, what i would like to know is, if anyone has uprated there heater blower? Mine sounds fine and im sure its going a good job for its age but wondered if anyone had fitted a better one. Many thanks guys. Tony. Share this post Link to post Share on other sites
Garry 1 Posted December 3, 2008 Intersted to see what answers come out of this. The fan on mine is crap compared to newer cars, the flow out of it flat out is the same as about half speed on my other cars. Not much fun when you are sat waiting for it to clear the screen (which is why I have my name down for the heated screen group buy). Share this post Link to post Share on other sites
pete1986 2 Posted December 3, 2008 I remember reading that you can get new ones from GSF, about £40 iirc. Share this post Link to post Share on other sites
GLPoomobile 958 Posted December 3, 2008 You could always replace the resistor with one of those eBay resistors. If it can give a 1.0 Micra an extra 15bhp just think what it'll do for a little heater fan! Share this post Link to post Share on other sites
kyepan 291 Posted December 3, 2008 serious answer, but a short one will reply in detail later, i've had no end of issues with the fan and the resistor, have got a hack for the resistor that i wanted to discuss. So far 2 months and counting i've got full speed at the fast setting, and no fan noise.. will pop back later wit more details and hopefully some pics Share this post Link to post Share on other sites
Rom 0 Posted December 3, 2008 Lmao I think youd struggle to replace it with anything else. Without modding how it sits / mounts etc. As anything else will no doubt be a different shape / size. A lot of the trouble is water ingress into the cabin. Which makes the window mist up more than it should, which in turn makes it a lot harder to clear. Iv noticed lately mine seems to have a mind of its own on high speed. Will seem quite slow, then suddenly kick into life and be a lot more powerful and noticeably louder. But thats another job to add to the list Share this post Link to post Share on other sites
DanteICE 72 Posted December 3, 2008 You could use a couple of caravan heaters, I have seen this done and they weight less and move alot more air and therefore heat it better too. Dunno if this info is useful to you? Geoff Share this post Link to post Share on other sites
kyepan 291 Posted December 3, 2008 (edited) right so a slightly longer post but have to pop off as still have work to finish, My Fan was playing up big time and it lost high speed, looked into the resistor and it was covered in muck. Also the old car had the noisyest fan you've ever heard. this is not really a how to mod your fan but how to get it working 100% tip top, which is plenty good enough to clear the screen of condensation on cold mornings. Firstly the fan. take it out with the three screws holding it in, spin the fan and check for play in the bearings, if it's nackered find a better one, if it's ok regrease or spray on WD40 and replace, reducing the rolling resistance with lubricant such as wd or grease will help it achieve top speed. The resistor is second, take that out with three screws but leave it plugged in, whack the fan on full blast then look for the clip on the back that holds a semi metallic disc (5mm in diameter) against the circuit board, if applying pressure to the clip to push it onto the board kicks it into high gear you've got bad connections. Now i've had one apart and just fudged it up, so i took another got a small zinc copper nut from my dads pot of small nuts, dipped it in vinegar for 2 mins to get rid of the corrosion on the zinc. then took the disc out from under the clip, cleaned the pcb with a cotton bud and a bit more vinegar, cleaned the disc, replaced the disc, put the nut on the disc so the spring was under more tension, then filled the nut with solder. This did the trick, there was a click from the solonoid in the bottom and the high speed mode cut in. Now, a disclaimer, this is a bodge so unless you know what you're doing, which i clearly don't steer clear, we don't even know what the disc does (except that across the multimeter it has resistance) so perhaps removing that and soldering it straight to the board will bump up the fan speed more.. however it could be there to keep the temps down so if anyone knows please shout.

davepug205 7 Posted December 3, 2008 Thats great were abouts is the resistor? Dave Share this post Link to post Share on other sites
kyepan 291 Posted December 3, 2008 under passenger dash, has a white connector block going into it with about four thick yellow wires, the resistor itself is the size of the end of a fag packet, black plastic with a rounded rectangular extrusion about half an inch long. it's usually fairly close to where the carpet stops.

tonycj 0 Posted December 5, 2008 Thanks for all the replies guys, im going to have a look at the motor this weekend, bit of WD40 and see whats happening with it. Tony. Share this post Link to post Share on other sites
