2000 RX with 105K. Been a great car with no problems but I have noticed the driver's window switch acting a little strange sporadically. If the window is partially lowered and I hit the switch to raise the window, it will go down. Mess with the switch and it will start working normally. This does not happen every time but has happened 4 or 5 times in the last 2 weeks.

Has anyone else experienced this? Is there a way to clean the switch and correct this or does it need to be replaced? How much will the dealer charge to change this? Is it a DIY project or do I need to take it to the dealer?

Thanks in advance for the feedback.

If a switch goes bad, it is not worth trying to fix it. Just make sure it is the switch.

How do I make sure it is the switch?

I am not sure how the switch is configured.

The simplest kind are single pole single throw. [Two terminals which are open till you throw the switch then the gap is bridged]. Simple to test ... just short the two terminals. They are the easiest to check as you can safely jump the terminals with the switch connected.

Multiple terminals are a bit harder to test and you need the understanding of what is connecting where and what should be isolating when,

What would I do... just buy the switch. Time spent figuring the test procedure and collecting the information far outweighs the cost of the switch. I am not a proponent of returning items, but if the product is still in a sellable condition you may take it back if it does not fix your problem. Do check the return policy ... at places it is different for electrical items.
