Question
we bought our 1999 caddie from a toyota dealership (used) and had to had to have them install a new blower to get the air conditioner to work. everything a-ok for a few months then, boom... blower not working anymore and don't trust them to fix. what to do?

Answer
Hello,

There are many symptoms the same, but the problems could be different.

The problem with getting a different make than the dealer sells can be an issue.

Could be a bad blower motor again. These days, parts are not as reliable as they onve were. The quality is not there any more.

If the blower motoe and fuse are good, car has to be scanned at GM dealer with what is
known as a tech 2. Scanning the computer system will diagnose the problem. This car has a number of computers in it. One being for the a/c and blower system. You could very well have a bad computer and Toyota has
no way of diagnosing such a problem.

Since the early eighties to present Cadillac has had three serious and common problems. Heater blower problems since 1980. Anti-theft issues since 1990-always answering problems with that little pellet in your ignition key and most common 1982-2010 never, never, never operate the emgine with the temperature gauge past 3/4 or you may end up paying over $4,000 for a new engine. There are no good engines available because of overheating.


I love Caddys. Have owned over 20. They are a great car!

I just wanted to give you a heads up on common problems especially not to drive it hot as so many people do costing them thousands

You will like the car. Lots of power and great mileage

i hope my answer assisted you. Would you please rate it?

Thanks

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
