Intermittent fan post resistor pack fix
 
Over last winter I completed the resistor pack fix using the lotus relocation kit. This is basically a plug and play kit, very easy to install once you're in there. Tested the operation, blower fan worked far better than original. Put about 300 miles on the car, worked perfectly. Finally got around to having the AC system vacuumed and recharged. After that I started noticing that the fan would occasionally cut out for a few seconds after starting the car. It would come back on with normal operation. Cut to two weeks ago, one night the fan would not operate at all. I put in the garage for a week and when I came back to it I suddenly had fan operation again, with that initial cut out. Drove it all weekend with no issues. Took the car to work yesterday morning and it worked, stopped at starbucks, and when I came out the fan again was dead. Hasn't worked since.

This is incredibly frustrating to say the least. I'm loathe to tear it apart again to look for loose connections, but I'm not sure what else it could be. Anyone have any other thoughts as to what might be the issue? The only other odd behavior that I've noticed occurred this morning when I noticed that the speedometer is suddenly sitting 10 mph higher than it should, at rest and at all speeds. This is probably unrelated as I changed out with my display faceplate over the winter, but I thought I would mention it anyways as it was something that was functioning properly and then all of a sudden isnt.

If the Orange wire at the blower isn't completely replaced by the kit, it is probably badly oxidized under the insulation. Does the kit include a new orange wire? The black wire is probably OK.

It's been a long time since my post, but I thought I'd put some closure on this. I pulled out the HVAC system and blower over this past weekend. No obvious problem, but I replaced the orange wire and sure enough it works fine now. I recommend that anyone installing the lotus kit also replace the orange wire from the blower entirely. It's only a couple bucks and it could save you a lot of headaches down the line. On the plus side, having done it before it only took a few hours to pull out the system, replace the wire and install. Clam goes back on tonight!

Was this resolved by doing the speedometer reset procedure?

Thanks for the warning, need to tackle this soon and definitely making note to replace this wire! :up:

It sure did. I was pretty sure I'd already done it, but I may have performed the reset procedure incorrectly the first time. It's been working as intended since.
