door lock problem 98 S10 blazer

Whenever it rains, the factory door lock relays continously trigger on this 98 S10 Blazer. It happens just sitting there or driving down the road. I have some experience (but not with Cheys) with the resistor trigger circuits and think it's posssible to be having crosstalk from the moisture in the doors to be false triggering the relays. Any experience with this problem? thanks, this is a great web site.

Hmmmmm Do you have an aftermarket keyless entry installed?J Rilla

If it only does it when it rains that is a pretty good clue, where did you tap the connection at? It could be just a strand of wire poking through the tape on your connection reaking all the havock Hymer

Oh I forgot to mention that there is no aftermarket stuff installed here. So I haven't been into the door panels yet. I was trying to garner ideas from you guys before I tear into it. It may be as simple as the moisture guard is torn or unsealed. I didn't know if this was a regular problem with this car or if I have the only one that does it.

Never heard of it before, but it sounds like a relay has a cracked housing or moisture is penetrating the factory connection some where. I don't remember where they are on that truck.. hmmm Blazers had it under the dash.., my guess would be to check under the hood at your relay box and just replace the keyless entry relays and or breakers in the fuse panel.. Good luck
