THank you for using just answer.
What year and model is your Lexus?
My car is 1999 Lexus GS 400.
It has 86000 miles.I take good care of this car.I only drive
7000 miles per year.
I put in a new water pump and timing chain last year.
A mechanic checked the fan switch,he said it is working ok.
He thinks there is something wrong with the electrical system.
Please advise before I spend more money.
Thank you for the reply.
You most likely have a sticking fan relay here. Some electrical diagnostics will be needed to better determine which relay is being energized to cause this. do you need some diagrams and checks to go into this system with?
How much do you think it will cost ? at a lexus mechanic not a dealer.
A diagram will help.
