I have a 94 Accord the AC doesn't work correctly.

I would like to know what the low pressure port should be and the high pressure port should be.

Yes I have the proper equipment to messure both pressures.

I have about 40 on the low side and about 200 on the high side if I rev the rpms way up it gets up to 350 psi on the high side which has me concerned.

 

No AC experts in here?

Think I may have found my problem but not sure hot to fix it without tearing the dash apart.

It seems that my hot and cold are mixing some. If I climb under the dash and manually close the vent all the way I get a good cold breeze. So I need to figure out whats preventing the vent from closing all the way.

I would still like to get the numbers for low side and high side.

 

Fix your air mix control door problem. The cable might need adjustment or replacement, or the control unit might be bad, or..... Your numbers seem fine. Before getting too caught up on gauge readings make sure you have a full charge. Low charges will make your ac blow a little warmer or not at all (basically because the pressure switch wont let the compressor clutch work) and throw off readings. Sounds like you found the problem though. No one is an expert, some just have more experience than others.

Thanks thats actually useful even though its for an odessey.

I wish they had some specs for different RPMs

 

Most often the temp **** strips out. About $6 at the dealer.
