2006 Suzuki Grand Vitara fan won’t stop blowing til the engine is off

The fan won’t quit blowing on high until the engine is turned off. It has less than 48,000 miles on it.

Which fan? The engine cooling fan or the heat/ac fan? If it’s the engine fan I’d suspect a bad temperature sensor or fan relay. If it’s the heat/ac fan probably a bad switch.

Thank you for the response! I’ll pass on the info to my son who will fix it for me. Honestly, I didn’t know there were 2 fans, I think this is the heat/ac.
Appreciate it.
