Auto rain sensing wipers during remote start - Gen1 04-09

[cwp_sedan]

This has come up as a concern since I recently had a remote starter installed.

On occasion I lift the wipers up when it's snowing or there is a chance of freezing rain. I have been careful so far but I know there will be a time when I forget to turn off the auto wipers and remote start the car and damage the wipers and/or motors.

Is there any kind of work around so that the wipers won't come on at all during the remote start or an alternative?


I know I can't be the first person to have this question/problem.

This is for mostly 04-09.

does that actually damage the wipers? running them while they are up?

I think what he meant is if he forgets to put them up and they are stuck, but auto feature turns them on when he is not around.

I cant remember, but cant you turn the auto wipers off

[parro]

I've had this happen to me once! Remote started my car after it snowed with snow on my windshield and my wipers down and it was set to auto.

Damage wasn't bad at all but I remember every time now to turn off my auto wipers! Easy to forget that they're on when they automatically stop.

I don't think there's a work around to this except making sure to turn them off!

My wipers are off all the time unless I turn them to auto. I miss intermittent. Lol.

I'm sure a few of the guys here that are good with wiring can figure something out to connect the wiper control to the???
I dunno maybe the DRL's. They only come on when the ebrake is off.

[cwp_sedan]

I'm not worried about a little snow.

There is actually a safety measure in place by Mazda, supposedly, that prevents them from overheating if they are stuck by ice, snow, etc.


What I am referring to is if you lift them off the window and leave them like that for say the day so they don't freeze to the windshield, etc. and then remote start the car with the auto wipers engaged.


Like this (example only as this is not a Mazda 3)

I'd still say my idea stands. Connect somehow to the drl switch. As long as ebrake is on they won't move.

how about turning off the auto-wiper?

No I agree but I was just wondering if compustar was setup that way if wired a certain way. It would make sense.

lol

Thanks Eric. That definitely would be the best option. :P

Oh. Ya that I don't know.

No such safety measure. Mazda actually mentions in the owner's manual about making sure wipers are off 'auto' in winter. Now I never have my wipers on auto, I hate the feature with a passion as the wipers always go nuts, I'd prefer the manual intermittant personally. I've been told the only way to eliminate 'auto' wipers and go to 'Manual Intermittant' is to change out the stock and main ECM.

that does not mean the linkage wont break though if this feature exists. ask Ash about that one haha

i dont see how that would make any difference at all if they are up and go off. only difference is there would be less resistance for the motor to push right? its still turning at the same speed and angle and whatnot. nothing has changed other then less resistance

install a relay for the auto wiper wire between the PJB and switch... that relay coil should be controlled by the remote starter which will disconnect the circuit when energised when the remote starter is active.... use a standard bosch SPDT relay which will let you have a completed circuit when the relay is not energised

Easier to just flip the wiper (right) stalk up to turn off the Auto wiper feature when you get out.

When you get in, easy to just flip it back down to the auto position.

[brucewayne]

i never use my auto wipers... they have a sense of their own and don't wipe when i want them to.

use aquapel instead and forget about wipers.... that is a great product that i will continue to apply forever.

sure it is, but the point of him asking was the fact that you *could* forget to turn it off sometimes!

lol +1

I'm just interested in the different options available if any. I figured a relay setup might be the only option but I thought someone might have done it before. Thanks for the input.

Not sure the tech did it, but when my handbrake is up, autowiper is disable, so when i use the remote start, because to enable the remote i need to pull the hanbrake witch mean the wiper is disable.

Sorry me english:(

It's probably like this for you because you have a manual transmission. Interesting though that they are disabled. Might be a newer thing.

This is what I did with my trunk popper -- it's only active when the handbrake is applied (it's triggered off of the door motors, and I didn't want the trunk opening if someone was playing with the door lock/unlock switch). Be dead easy to intercept the auto-wiper wire and use a relay to control it. I used the parking brake switch as the ground input and spliced a diode into the line going to the PJB to prevent current from being pushed into it. I *think* I used the door motor as the +ve, but for the wipers switched +12v would work - that would eliminate parasitic draw when the car is sitting. Run the wiper connection through the NC contacts and you're good to go.
