Odd A/c Problem

[stswulf]

When I turn on my A/c it is slow to cool and leaves a nasty film on my windows on the inside…looked under the hood and just below the windshield –line there is what looks to be a missing plastic part that covered a inspection hole.

This hole blows out air, and when covered the A/c blows harder. Wondering it I should cover it and with what… that will take care of the film as well

Is it near the words "Cut Here" on the blower box?

I got the "nasty film" all the time right before my heater core went out....Dealership replaced the heater core a total of 3 times....I can't stand that film ...lol

Do you notice a sweet smell almost like a maple donut? If so, you should replace the heater core before it pukes coolant all over the carpet.

stswulf,

There is a small rectangular plate that should cover that hole. I would get some Aluminum autobody repair tape & cover the hole up. That should solve your slow A/C problem.

As far as the film on the windows, it still could be a heater core. Are you losing any antifreeze? If so, I would get that core changed out before it blows & leaves you stranded. Be sure to get one that has the metal tanks instead of the factory one with the plastic tanks. I bought one at AutoZone for less than $40.00 & they had it in stock. It fit fine and I was actually surprised at the ease that it was to change.

thanks guys yet again you guys come thru

im not loseing any anti freeze and , but if i cover the holw up and it does not clear up i'll look into the heater core

you gus are better than.....

[navion]

It dosen't take very much anti freeze to cause that film to form.

I am amazed that someone would cut that panel out to clean the evaporator and not patch it back up. That's kind of like drilling a hole in your garden hose and wondering why there is no water pressure. Like Navion said a good heavy guage aluminum tape should make it as good as new. Like everyone else I agree that it should have nothing to do with a film on the windows and that is very indicative of a leaking heater core.
