so you talking about the outside fans under hood or your fan in car? if your talking about the raitiator fans yes they do. also i might say don't turn air on hi all the time it will colder in between on your fan inside it cools it off to fast running it on hi like it's not gertting cold enough for you. may i ask why your asking this?

Assuming it's hot where you live to check low speed just run the engine and look at the fan spinning. At high speed no need to look as you will hear it (if the vehicle is parked). You can force it into high speed by setting temp to max A/C

Dear Windstartled,
Thanks I have noticed that when I start after some time both Right and left fan run at the same speed and when AC is on they will run contineously with out chang of speed but high speed.
In my manual written relay 301 and 303 are not used while most of the net information says it is for high and low speed of the fan.
Best regards
