I have been trying to replace my regular bulbs with LEDs, mostly for the look. I replaced the H3 fog light bulbs with some LED ones off Amazon (Auxito brand) only to find out they are polarity sensitive and don’t work. I put the regular halogen bulbs back in. Does anyone know of a brand of LEDs that are polarity neutral that would work? Thanks.

Hello, I am new here and hoping someone may be able to steer me in the right direction. I have 2004 rx330 that was blowing the turn signal fuse, I did not realize at first that it was the fuse, it stopped charging so I replaced the battery and the alternator, then found that if the turn signal fuse pops the alternator stops charging, I replaced the multi switch and thought it was fixed, but after about 50 miles now it popped the turn signal fuse again and alternator stops charging, as soon as the fuse is replaced the alternator charges again. I hope someone can tell me what * am missing, please?

The fact that the ALT fuse blew immediately and there was a visible flash at the alternator is a strong clue. Before installing another fuse, I'd recommend finding the cause first, otherwise the new fuse may blow instantly as well. Here's what I'd tell the owner: Things to check first1. Verify all alternator connections Make sure the large charging cable on the alternator output stud is installed correctly. Confirm the plastic insulator is present on the output stud and that the cable terminal is not contacting the alternator case. Inspect the connector plug for bent terminals or damaged wires. 2. Look for a pinched charging wire Follow the heavy cable that runs from the alternator to the fuse box/battery. If the insulation was damaged during installation and the wire is touching metal ground, it will immediately blow the ALT fuse. 3. Disconnect the alternator and test Leave the alternator electrically disconnected. Install a new ALT fuse. Reconnect the battery. If the fuse does not blow with the alternator disconnected, the alternator itself or its wiring is likely the problem. If the fuse still blows, look for a short in the charging cable between the alternator and fuse box. 4. Check the replacement alternator It is not unheard of for a remanufactured alternator to be defective out of the box. If the flash came from inside the alternator, there could be an internal shorted rectifier diode or regulator. 5. Double-check battery polarity Verify positive went to positive and negative to negative. Even a brief reverse-polarity event can damage an alternator and blow the ALT fuse. One important questionDid you replace the alternator yourself, and if so, was the battery disconnected before removing and installing it? Also, was the blown fuse the 120A ALT fuse in the underhood fuse box, or a smaller charging-system fuse? The answer can help narrow down whether you're dealing with a wiring short or a failed replacement alternator.

On the 2010-2015 RX350, the hazard switch is part of the center dash trim assembly above the audio/climate controls. If the button itself has fallen behind the trim, you'll usually need to remove the center vent/clock trim panel to retrieve it. Typical procedure: Turn the vehicle off. Using a plastic trim removal tool, carefully pry up and remove the woodgrain/silver trim pieces that surround the center stack. Remove the center air vent assembly and upper trim panel. It is held by clips and, on some versions, a few screws exposed after trim removal. Reach behind the hazard switch opening and look for: The hazard button itself. The switch assembly that may have become detached from its mounting tabs. Reinstall the switch into its bracket. If the plastic retaining tabs are broken, the hazard switch assembly may need replacement because it will not stay secured. Reassemble the trim pieces. A few important points: Do not push a screwdriver into the opening trying to fish the button out. It's easy to scratch the dash or damage the switch connector. If the hazards still function when pressing on the fallen switch, the electrical portion is probably fine and only the mounting tabs have failed. If the button completely separated from the switch body, you may need a replacement hazard switch assembly rather than just snapping the button back in. For a 2015 RX350, this is generally a 15-30 minute job for someone comfortable removing interior trim. Can you tell me whether: The entire hazard switch assembly fell behind the dash, or Just the red button cap disappeared into the opening? That will determine whether it can simply be retrieved and snapped back into place or if the switch housing has broken.

I've been using 5W-20 in my 08 Miata for over 13 years, and I don't always baby the car. It's never consumed a drop of oil. Our Camry uses 0W-8. That oil was tested by Toyota in 110-degree F ambient temps. I am fully confident in it. My Supra uses 0W-20, but it has a turbocharged six cylinder engine. I am going to send out some of its oil to Blackstone Labs have them analyze it. If you are concerned, you can do the same. You can request a test kit that includes a container into which you can pour used oil from your oil change.
