SOURCE: lexus heater blows cold

You could have a blocked heater core. Check for two heater hoses running into the firewall in the back of your engine. They should be together and about 5/8" in diaameter. If one is hot and the other is cooler then your heater core is blocked. Unhook both hoses and use a garden hose to back flush. Be sure to catch the coolant and dispose of it properly.

Fuse blows as soon as you incert it into yhe ignition circuit on my C300H countax

You have a short somewhere and you need to trace the wiring. For your diagnosis, use "circuit breaker" fuse which will auto-trip/reset if there is a short or high amp draw. I even replaced some of my fuse with circuit breaker.

My power window and door locks fuse keeps blowing.

When the fuse blows figure out what you are doing, what switch is being pressed, then remove the needed panels to access the wiring to the switch and motor it operates, then you will find the damaged wiring and repair the short, no quick fix, just hard grunt work.

Horn does not work on my 1994 Lexus E300

Horns are nothing more than an electrical coil that has a set of points to open and close the circuit. This sucks the horn plate in and out giving you the sound. If it is blowing fuses check the wiring for shorts to earth and if ok replace the horn as the coil has probably rusted up and has a dead short inside.

My internal lights keeps blowing 10A fuse on lexus is250 sport (2006) model..takes about 3 hours from when you put in the new fuse.

Are the globes you are using internally the correct rating ? Normally a short will blow the fuse immediately.

Also are you sure the 10A fuse is the correct AMP rating ?

Doulbe check both these with either your owners manual or a Lexus dealer.

If both these are correct you will either need to trace, test and check the related wiring yourself using a standard voltmeter (from fuse contact in the fuse box to the globe contact). Check for stable currency and AMP readings. Note the AMP readings for the answer to the above questions.
Auto electric are generally a nightmare, with all the various colour coded wires running inside wire harnesses, making them difficult to trace with out a full wiring diagram for the vehicle
have an auto electrician check it out for you
