This is a 1993 car… The blower fan squeaks at start up and is worse with the cold.  Last winter my mechanic gave it a shot of some lube material but it did not solve the problem.  I asked him for the part number which he gave me and found them blower motors only for a hundred dollars.  He is telling me it will cost me $600.00 to fix this problem.  What am I missing?  Or is he trying to gouge me?  With winter approaching I would like to get this fixed.  But $600. seems high.
 The other problem is with the radio.  It died last winter, but returned during the summer months.  The mechanic says the whole thing has to be replaced, but I question that diagnosis as well.  Maybe a short or a poorly insulated area.  Cold is the problem.
 Thanks for any input or advise
The high cost to replace the motor may be due to a lot of labor time to get at the motor. I have never replaced one but some vehicles are a lot harder to work on than others. You may want to ask some other shops for a repair quote to see what they say about the cost of repair.
The radio problem may be due to a faulty power supply wire to the radio or the radio could have internal problem. The trouble area needs to be located before replacing anything.
