It did this for about 2weeks, sometimes it would do it, sometimes it won't. Now its all the time!! If you just turn the key on, Light will just stay on and won't go off, once you start it, it flashes on and off!!! Anyone know anything about this?? Its a 98 12v, Thanks Chris

 

don't know if a 98 is same as a 92, but on my 92 if you unplug air temp sensor (thermistor), wait to start light stays on for full 30 seconds, (so does grid heater), regardless of temp, then wait to start light flashes. Unplugging the thermistor is actually the test procedure for the thermistor. Try checking thermistor connection.

 

Oh man, this sounds bad...

 

It could be a bad relay.

 

yep sounds like a possible heater grid or controler kinda like ABS light
flashing a code .

 

Did you check for any code's.

 

Well i think i found it. Its the Air intake temp sensor. Tried my budies and it takes care of it!!

 

Wow, props to Matt Auge!
