2006 Lexus IS 350, 100K miles, A/C runs cold then runs warm. Dealership told me they would perform a/c pressure & leak test for about $170. after a few days I would return and they would check for leaks.
Instead, they said they found coolant leak around water pump and recommended water pump replacement for $1200. A/C has been operating intermittently for 2 seasons, but never any indication of water pump problems. I declined repairs since I was surprised at the diagnosis and stunned at the price. The technician advised water pump problems could occur even though none had been previously experienced.
Drove 45-60 minutes home with no problem. The next time I drove the car was 4 days later and, sure enough after about 45 minutes and miles from home the engine light and vsc light came on and there was noticeable vibration. It took me 90 minutes to creep home at 20-30 mph and I smelled coolant.
I hate to accuse, but I don’t think anything was wrong with my water pump til the dealership messed with it, and how do I know replacing the water pump will fix the A/C problem if the pressure & dye test was not performed.
What do you recommend as next steps. I don’t want to go back to Lexus. Is it OK to drive the car about 6 miles to a neighborhood Goodyear car repair shop and get another estimate?
