Exige with non working heater blower

I have a 2007 Exige S. and when i took it out of winther hibernation, the heater fan do not work (it was working fine when i parked it) The car is stored in a dry and heated garage. I have searched the forum, and the thing that comes up, is the fan resistor. It has the symptoms, but i have never smelled any thing burnt. The fuse under the dash is ok. Is it possibile to get to the wiring to the blower motor, to check if there is power in to it (i can see some connectors down there when i take of the covers in front of the windscreen) I also read that someone bypasses the resistor, and only runs the fan at off or full speed, can this be done without taking the fan out of the car? Removing the front clam is not a big deal, i have done that a couple of times before, but the part with taking out the fan looks to be a bit more work and complicated. Would like to get this sorted fast, as the driving season is starting.

The only way to do it right is to remove the clam, evac the AC and remove the heater assembly

It is possible tho probably tedious to get the fan connections through the recirc vents forward of the pedals[LHD]

There is a largish black plug under the access panels, probably ty wrapped to the harness along the forward edge of that compartment that you can test whether there is power getting to the fan

Ok, i will take a look. But what about bypassing the resistor, can that "easy" be done. If so i would like to do that temporarily for the summer season, and do the big job in the winther.

Do there exist some pictures that show where the resistor sits, when the blower is in the car, and why it can not be swapped without taking it all out?

the blower is right in front of the drivers feet, on the floor

the resistors are on the bottom

search for one of the many threads[mine included] and there are adequate images

If you remove the cover over the recirc vents[drill 2 rivets] you can 'see' the blower through the holes, but touching it, that is a whole nuther thing

Anyone know about the bypass, if it is an "easy fix"

I have removed the front clam (quick 45 min job) but does anyone have a description to how to get the AC lines out of the expantion valve, that sits over the HVAC unit. I am going to go all the way, and installing the upgraded restor pack.


PFA (i got a LHD car)

One bolt between the lines clamps the lines to the block

I would recommend against using the factory resistor replacement block, it further restricts air flow, if I understand its installation.

Ok, the job is done, and the car is ready for summer and many trackdays (first one at Spa Francorchamps in the end of may, and after that some days at Nürburgring)

Actually this job was not as PITA as i thought it would be, after reading about it online. I got a little help from my son in law, that popped by, and the whole job was done in just under 4 hours, including the clam off/on. Only had to go to the garage to fill up the AC again. And now the heater is better than it have ever been. I got to clean out both the fan, and the radiator in the heater box, that had quite alot of grime in it.
