How to soup up windsheild wipers, and heater fan?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

masterbeavis · 09-10-2005, 10:36 PM

my wipers are SLOW (for me anyways) and the blower motor, once I hook it up, will be too slow for me as well. Any tricks to soup em up and make em faster?

jhow66 · 09-10-2005, 10:57 PM

Wipers--disconnect wiper levers from motor and check to see if they move freely-if not remove wiper transmission and soak in WD-40.
fan--replace with one off AC truck.

buy a new blower motor. They are $20 at Napa.

Make sure your heater fan control lever is working properly. I went for a few years wishing my fan worked better. Then one day I pushed my heater control lever over to the right a little harder than usual and the fan kicked into high speed! I felt pretty dumb. I didn't realize there were three speeds for the fan, controlled by the switch and the resistors that are mounted on the top of the heater box.

Add an extra battery and run them on 24v. They may not last long but they will sure run faster!

Why dont you try it out first and let us know how it works out??

If the wiper motor isnt jammed up, how can I get more RPM's out of it. Is there a different application, or a manufacturer that makes somethin faster or better?

tylermckee · 09-11-2005, 03:42 AM

my wipers go plenty fast, i just wish i had a few more speeds to them.

Have always had good, hot, hard blowing heat

and btw, what are wipers?

bobs409 · 09-11-2005, 06:51 AM

It could be your wiper motor is going out. Mine started going slower and slower towards the end. I replaced the motor with another used one and they work nice and fast now.

70GMCer · 09-11-2005, 07:40 AM

I found out one thing that causes the blower motor to slow down.....A mouse nest inside the heater box.......

Alan Potter · 09-11-2005, 09:07 AM

...only drive when it's warm and not raining???

Running an A/C blower can fry the harness. It pulls more amps then the non a/c one, and the wires aren't rated for it.
Do a voltage drop test, and see if you are getting a good ground.

86swb · 09-11-2005, 04:26 PM

Thanks Longhorn Man. I was thinking of getting one of the A/C blowers myself. Now I know not to. Do not want to fry my wires or worse.

pound41 · 09-11-2005, 04:34 PM

If both are slow check the grounds Try taking a jumper lead and grounding either motor before turning it on. The grounds are a common problem

masterbeavis · 09-11-2005, 06:00 PM

well, it is an AC cab, the motor doesnt work at the moment, havent tried anything "yet" I have never seen "fast" wipers. I have seen several trucks, they do not impress me. Maybe its a california thing?

What are your thoughts on intermittent wipers?? Was there a factory option, or is there a way to finagle em in using something else?

Robert1970C20rstbukt · 09-11-2005, 06:03 PM

The original blower motor in my truck was so wore out it was melting the orange power wire coming from the fan speed switch. I could only use it on the 2nd speed, and it was pulling about 10 amps. High speed pulled about 20!!!! Changed it out with a used, but newer Delco motor and it hauls ass, but it heats up the wires too. I know I'm gonna end up buying a new one, I want to get it fixed before it gets cold. Gotta get new heater hoses too.

There is always a way to make it fit. A friend of mine put an old dodge blower in a 70 chevy, and said it was great. But both him and the truck are long gone, so I can't get specs. My heater motor quit last spring and until the last week I had forgotten about it. But cold comes hard and fast at 7000 ft. and we're starting to freeze almost every night in the valleys. Time to investigate the cause...before I freeze my a$$ off.LOL

Does your alt work?

Gordo · 09-11-2005, 10:06 PM

When checking the blower motor also check to see if the defroster hoses are in good condition and attached on both ends. They could be damaged or not connected.

Hey Long'Man-got ac on mine (factory) and it has 14 gauge on all wires the same as the heater only on my ex 72 truck. (diagram shows 14 gauge for heater--14 guage is plenty to carry a ac fan. (now I could be wrong

)

Give the hampster running the little wheel some performance enhancing drugs
and watch it go then!

71-longbed · 09-12-2005, 12:48 PM

try cracking a a kick panel vent while using the blower ... if you have a good sealed cab ... it blows harder when in cab pressure is released
