John Bonness 73123 Posted August 7, 2018 Report Share Posted August 7, 2018 Has anyone experienced a check engine light caused by the heat exchanger fans coming on? The last few day I start my 14 Snake and within 10 seconds the heat exchanger fans come on along with my engine light. I looked at the inlet temp and it showed 79 degrees.

twobjshelbys Posted August 7, 2018 Report Share Posted August 7, 2018 What was the code? If you don't have a OBDII reader (I recommend a bluetooth reader and the Torque app for Android), then take your car to a parts place like AutoZone and they will read the code for you.
