My conversion from the original 2 speed wipers to the upgrade intermittent wipers worked great initially. While driving in the rain the delay feature stopped working. I have checked my ground and connectors but I don’t find anything wrong there. I’ve replaced the new LMC module to get the very same results. The wipers run fine in slow and fast and in intermittent. Just the delay stopped working. Any input to help me find the problem. LMC has been generous to supply another module but now has basically told me to check grounds and connectors or they will refund the purchase price. No tech support these days. I loved the delay while it lasted. What could I be missing. I don’t want a refund. I want intermittent wipers. Thanks in advance for your input. LMC says there’s been plenty of these modules sold and no other customers complained of failure.
