I have an 09 XC90. I'm getting a high pitch, intermittent squeak coming from the drivers side windshield wiper post. It occurs for 4-5 cycles, goes away for maybe 20 cycles, and returns. It happens with or without the blade attached. I sprayed some silicone lubricant. No change. Anyone have any ideas?

What brand of blades do you use ? There might be a fitment issue, had one of those myself.
