99 Miata turbo. Running MS2. Car eventually overheats at idle & when driving. I think some of the cause is lack of ducting for now but I noticed my fans do not kick on. Not with A/C either. I also went into TS & set the output coolants to 180 degrees & that didn't get the to come on either.

 

jump TFA to GND and see if your fans work at all.

 

^Nothing after jumping. I noticed when A/C is on, passenger fan comes on. Also noticed my horn does not work either now.

 

looks like you need some new relays.

 

H270 relay?

 

I can get the fan to come on when I attach my jump pack to it. I'm so stumped with this. Where is the relay for this fan?

 

I started wiggling pretty much everything. Got to the fan connection & it kicked on. The connection is really loose. I sort of tightened the connection & put some dialect grease on it. Works good now but I went ahead & ordered a new connection.
