ace -> Intermittent wiper problem, ETACM (3/21/2008 9:35:33 AM)
|
I have a 1999 Elantra and the intermittent wiper control and park position does not work. The slow and fast speeds work fine. I have checked fuses and motor works fine (connected up spare working motor, and verified it worked, only on slow and fast wiper speeds as well). I do hear a "click" behind the ashtray (ETACM?) whenever I switch on the wipers for intermittent, slow or fast speeds.
According to the schematics the ETACM is responsible for the intermittent wiper, timing control, and auto parking. I need to first get to the module (in back of ashtray/radio), check the power to it, the grounding, and possibly replace it.
My question is which electronic module is it behind the radio, upper one or lower one? Each one has a multi-wire connector. Both boxes have a sticker label HMC One is stamped "AT" (w/18 wire connector) the other has a 20 wire connector. Any other concerns I should be aware of?
Thank you, ace
