As the title states... I have an 04 Accord EX 4cyl. not dual climate. The drivers side vents blow warm air and the passenger side is cold. I've searched quite a bit on here and on the internet in general. I've found similar complaints and suggestions as ti what it could be.. Anyone have any new info more recently or anyone actually had this problem and had it fixed? Much appreciated

Anyone? Any help would be appreciated. Thanks.

A low charge in the a/c system could cause this to happen. You would have to get the pressures tested on high and low side of the a/c system to verify. If you have a low charge, then you will have to repair the leak, then recharge.

This is based on my 05 TSX, but another possibility is that the air mixer for is not working on the driver's side. You would need to test this.

Are you planning on doing the work, or taking it to a shop? If you want to DIY, I highly suggest getting a shop manual. I bought one in pdf form for $21 from automanualsource on ebay. It is very detailed and helpful.

In the DIY section, there is a way to have the HVAC system do a self diagnosis. I copied the link below:

I have a dual climate Honda Accord and I didn't think it was the freon charge that was causing the passenger side to blow cool and the driver's side hot.. but they checked and it was a little low and after charging it up its fine again.

So anyone looking this up, I'd advise getting the charge checked first, cause it really can cause this problem..
