20 Most Recent 2003 Lexus RX 300 Questions & Answers


There isn't just one cause for this symptom. Is the engine light on while it is running? If so, please have the codes read and forward them. My first guess for "Hunting" is timing. The timing belt may be loose or the crankshaft sprocket could be loose. There could also be an electrical issue with the fuel system, ignition system or a component related to the ECM. Please write back with more diagnostic information and I will do my best to help.

Replace the master switch. Or you could take it apart and sand the contacts for the lock. Many and small pieces.

Assuming you are not sitting on the key fob when this is happening, I think you must have a short in the wiring in one of the doors. Open the doors and check the wires that run from the body to the doors for any broken wires.

You may not be able to do this with a key, and if you can most are done by inserting key into the ignition and turning key to on.

Why have you not had the vehicle at a shop, so they
can check the systems for codes & at least find a problem?

You clear dash lights,you clear ALL the data needed to work on
any vehicle, until the lights come back,codes return or emission
monitors run

You don't

Have a shop test the system for leaks

No point in hurting yourself,letting air into the system,
to over charge & ruin it

If you have to add, it will leak out again,will it not, & continue
to pollute the air as it is now doing

Those cans should not be sold in stores

You need lot of knowledge/training in the law of physics
pertaining to refrigerant, to work on a/c systems

Freon WAS a Dupont trade name only & no longer used

They don't even own the refrigerant part of the business,it
has been sold to a hedge fund or capital management firm
