I would like to replace my default wiper switch that has Delay; Low; High, with a wiper switch that has more more intermittent delays. I have found the actual switch that I would like to use for the model of my car. Can I just replace the old switch with the new switch without replacing the pulse module or wiper motor? ---

My guess is no. I could be more accurate if you supplied model and year of your vehicle. I give a very confident no to the question about the need to replace the motor. Think about the possible need for a different harness. Why would you consider that it would be possible to give a good answer without this information? Everyday we must ask people to provide this type of information. ---

My DeSoto has the same problem. ---

Depends…Year/Make/Model. When I bought my 90 Pathfinder in order to get Intermittent wipers I either had to buy the SE version or get one with an Automatic. I didn’t want either. Nissan did sell a intermittent wipre kit. I had to replace the switch and add a power boost. It worked great. And the good thing it only cost me $50 as compared to $300+ for the Automatic or SE model. ---

the reason I think it is possible to replace the switch without replacing the motor or pulse module, is because when I shop online for parts, all I can find is one motor and one pulse module for my model of car, but I find two different switches (the standard one I have, and one with more intermittent delay options) ---

Actually, your DeSoto was probably ahead of the pack with its windshield wipers. The 1947 DeSoto my parents owned had electric wipers. The 1968 AMC Javelin I owned still had vacuum wipers. Of course, the vacuum wipers had many interval settings–you had to release the accelerator pedal, thus increasing the vacuum, to make the wipers move.
