I have a 97 ls400 that just recently had the ac only blow on low cold but i can still change the settings to whatever i want, but nothing happens, but strangely the radio does not work either, even weirder when i go higher speeds the a/c and radio turn off and on over again, eventually turning on til the car turns off and on. I’ve checked the fuses in the hood and under the dash? any ideas? i’m selling this car soon and need to understand what’s causing this.
