AC is stil running well 12 days after service and recharge (better
than last time as we have had 13 days over 90 degrees and high
humidity, but only had one last Summer.)
Anyway, in town the temp out of the vent is 52 to 54 degrees farenheit
when measured with a digital probe. (11.11 to 12.22 celsius.)
Have not had a chance to check it yet on the highway for an extended
run, but a tech I know says it should be reading 38 degrees farenheit
(or 3.33 celsius) on the highway-or a bit lower.
The tech is a friend who builds race cars and is not an AC specialist
but has a shop where he repairs "exotic" cars. The man is as sharp as
they come, but seldom works on Volvo and has never worked on a Volvo
I do know it's not gotten that cold and am wondering what others are
Figure 90 degrees f and 70% humidity (32.22 degrees celsius) for
ambient outside temp to make a comparison.
Now for the rear wiper motor question:
The "so-called" new wiper motor I bought from a guy on Ebay failed.
Took apart the old one and found that when the pinion shaft froze the
plastic brush carrier inside the motor had actually melted on one
side, so the brush could not make contact.
The new one is now dead, and when tested draws no current--so I
suspect the same issue.
That said..does anyone know where to get parts for these motors? I've
had no luck on the net or with local motor repair shops.
Sort of ticks me off as the repair involved would take me about ten
minutes (not including re-installing the unit in the tailgate) if I
could get the parts.
To be on the safe side I did buy a new wiper control arm (Dealer calls
it a transmission for $110.01 plus tax.) A new motor is over $200
USD, and until a few minutes ago I had found none available as
aftermarket or rebuilt on the net.
So here's a tip for anyone in my situation: I checked again this
afternoon and http://www.rockauto.com
has rear wiper motors for the
93 wagons for about $78 USD. THe units are remanufactured by A1
Cardone, a name many of you may be familiar with if living in the US
While I'd prefer to buy the parts (probably not more than $20 if
available) and repair it myself--at least I'll not be stuck with
forking over $228 USD for an OEM unit from the dealer.
BTW...I've spoken to someone who really knows (he's a parts manager
for a Volvo dealer and restores older ones as a hobby) regarding the
wiper transmission. I'd used PB blaster and lubricant and thought
mine was OK--and it still seems to move freely.
He advises that he's been through this more than once and burned up a
few motors when the trans failed again. Bottom line appears to be that
if the transmission and pinion shaft are stiff or seized it's time to
bite the bullet and buy a new one. As he has been doing this for 25
years and is not selling me the part I take this advice seriously.
Sadly, not every part can be repaired.
