A/C does not blow...

[Nick McCardle]

So, to go along with my little gauge lighting problem my A/C does not work. No matter what setting, it does not blow at all. Brand new blower motor, all connections seem good. I'm clueless and any help is greatly appreciated.

this happend to my mc ss a while ago. Ended up getting 2 bum (brand new) blower moters in a row. I went to a junk yard and got a used one... slapped it in, fired righ up. Test the blower moter if you can. Probobly not the problem, but could be... never know.
after i got that fixed... 2 weeks later the heater core went. fun fun!!!

New update. Tried grounding the blower motor with a new wire and it worked. However, still some A/C issues. It blows on low, med-low, med-high, but completely turns off on high. Also only blows through top and bottom vents towards floor and windshield, does not blow through center vents towards seats at all.

The high speed relay is bad. Go through this post and look up one about this issue last week.

Relay is availiable at autozone for about 10 bucks... I put one on mine 2 days ago working an looking good !

Alright, got the relay ordered and will be in tomorrow at Advanced. Ideas about not blowing through the middle vents?


Thanks for all the help guys, I really don't want to drive my baby all sweaty.

When there is no vacuum availble to the heater/AC control, the default position for air is through the defrost vents. Check for a vacuum leak in the engine compartment (just prior to entering the passenger compartment on the passenger side of the engine compartment). If vacuum is present where you checked, the leak is somewhere between there and the vacuum control behind the heater/AC control.

The AC control can crack and leak as well :tongue:

Have it blowing on all settings now, just still not through the main vents. I'm working on it, looking for the leak.
