88 New Yorker- SLOW turn signals????!!

I checked my battery voltage = 12.5 v.
With engine running, wipers and turn signals on = 14 v.

Now what?

 

Yup. They are coils - at least a coil. Or a bunch of coils in series ,
concentrically wrapped - or co-axially wrapped - or what ever.

You are just being picky.

 

BTW my hazards flash at a normal speed all the time even with car off.

 

Then your problem has nothing to do with the charging system. Look
carefully for burned-out bulbs front and rear -- remember, this car has
2 or 3 bulbs on each side on the rear, all of which should flash -- and
if replacing bulbs doesn't help, then you've got one or more faulty
wire(s) in the system, probably at or near one or more bulb socket(s).

 

Sorta like I'm "picky" for insisting on proper diagnosis, compared to your
"Just replace the condenser, evaporator, radiator and entire rest of the
cooling system all at once because it's less hassle" approach.

I can live with that.

 

Possibly the wrong bulbs? Using 1034 instead of 1157 bulbs was a
common cause of slow flashing signals in days of yore. (1034 bulbs
were lower wattage versions of the 1157 bulb. There is/was a higher
watttage version as well - cannot remember the number offhand.

 

Except that 1034 bulbs have been scarce as heffalump teeth for a couple of
decades now.
