Okay everyone, I've been havin problems with my HVAC system.
Yesterday I was drivin down the highway and felt a little hot air comin out of the vents (barely any although the selector was on high), so I switched the temp selector to cold just to see and sure enough it cooled down. Then I changed the vent selector to heater and the air came out of the heater vents instead, so I know it's not the vacuum leak I thought was the problem before.

I've been told to check the brown wire that supplies the 12V and it appears to not have been burnt at the connector, I'm gonna test it again just to make sure, but I want to check to see if something else could be wrong too. I'm thinking the only other options would be a loss of power to the switch or to the blower motor itself, or a bad blower motor.

In either of the 3 cases, how should I go about finding out which one is the culprit. Thanks in advance.


if it is the blower motor, how hard is it to replace by yourself and do you needd anything other than basic sockets and drivers to do it?

I'm half falling asleep right now, and I don't fully understand exactly what your car did, but no, the blower motor is not very difficult to replace. It has a plug near the top, a rubber hose on the side closest to the engine, and its held by five little screws. You are going to need a short wrench though cause the bottom screw is in an odd spot and you can't put a ratchet on it.

Take my advice. Tie a piece of yarn on one end to whatever tool you are using and the other end to the hood hinge or something like that. I dropped the wrench too many times while I replaced the blower on my car. It took 3 three times as long as it should have.

Edit: Dam, sorry for replying, I didn't realize the date on this thread until later.

 

ROFL, that post is over a year old...
