So I have a 2017 RDX. Wipers did not work at all at first. Found an issue for underhood wiper relay ground #302 was bad on driver frame rail. Also was the cause of my blower inoperative.
now I have just one speed on the low and high setting. Seems like high speed. But intermittent and low speed noyworking and also will not park.
i am trying to locate the intermittent relay and HI/Lo relay as well as theory and operation of the wipers.
Zeta,
thank ypu fpr the reply. Do ypu happen to have the legend that will identify each relay in the distribution box?
relay 11 was the one i had issue with the ground. But ot seems like there is a HI /Lo and intermittent relayin the circuit
So I found all the relays and determined which terminal is which. I can put power to high speed terminal at relay and low speed at relay and the motor works at proper speed with jumper.
but need to find a diagnostic chart to pinpoint why I don’t have intermittent wipe or low speed , also will not park. I have a scan tool and seem to be getting proper reading from switch but can’t activate wiper from functional tests

Got a diagnostic/pinout for you.
This is all going through the MICU (Multiplex Integrated Control Unit), which is that crazy under-dash fuse box with everything connecting to it.
