NC85ST Posted April 20, 2019 Report Share Posted April 20, 2019 I have two 85 ST kingcabs, one has a fixed interval intermittent wiper switch and the other has a variable interval intermittent wiper switch. So the question is can I change out the fixed interval switch for the variable interval switch? Or is there something else I need to change as well? 1 Quote Link to comment
Lockleaf Posted April 22, 2019 Report Share Posted April 22, 2019 They will bolt in place of each other but the variable function will not work unless you also relocate the "wiper amp" which is up under the dash. 1 Quote Link to comment
NC85ST Posted April 23, 2019 Author Report Share Posted April 23, 2019 Thanks. I figured there was more to it than just swapping switches. Now I just have to find the amp. Quote Link to comment
datzenmike Posted April 24, 2019 Report Share Posted April 24, 2019 I think those are the two options fixed and variable. There are also fixed and variable amplifier boxes so if switching from one to the other you will need to swap the box also. 1 Quote Link to comment
Charlie69 Posted April 24, 2019 Report Share Posted April 24, 2019 There is the non variable in the base model trucks. Quote Link to comment
