I was in Walmart yesterday, it was $8.00.

The cheapest R134 I have found is 11.00 a can but that is in an auto parts store.
I guess I need to check Walmart next time.
The gas isn`t expensive, but if you have to get it done it can quickly add up.
In my experience it seems there are two tiers to shop repaired AC systems.
It`s either going to be 500.00 if they don`t replace any parts or 1000.00 if they have to replace parts.
To me it`s worth it to get the gauges, a vacuum pump and the knowledge to work on it yourself.
There are enough people on here that can give you the knowledge to save you a lot of money.

Thanks for posting this. I only recently saw that this area had a panel that looked like it could be removable. I thought about opening it up to check for a mouse nest but I had decided against it. Looks like I decided wrong again! I didn't even know that little radiator-looking thing was in there. So what do you call the big radiator-looking thing in front of the actual radiator?

The one in front of the radiator is the condensor.

And you are right Joe, my evaporator had to be removed as the stuff was so caked on I used grease remover and had to spray water in from the other side to get all of the goop out.

Here's what I found in mine. This is an original 23K mile car that spent most of its life in a garage.



If this car has it, your car has it!

Now, how do we stop it from happening again? Stuff foam around the front trunk latch?

GM though so... This is OE in 87...

The area around the latch is just one way for the debris to get into the cowl area. After that it has to jump a little wall and fall through the hole that sits rearward of the latch. The latch does not sit over the hole to the air inlet. I'm thinking of adding something over the actual hole. Would a sceen or some kind of very low density foam be better to cover the inlet hole? Maybe a combination of both?

I think it all depends on where you park your car a lot.
I figure mine took 24 years for the stuff that was in there to accumulate and now that I have moved, my car is always under a carport.
Plus, wherever I drive it, to work and most places, I don`t park under any trees.
I think if you periodically check it and maybe vacuum out through the resistor hole before it has a chance to get caked on, it will be ok.

Watch wiper pivot when that is on... pivot assm and the link moves plenty.
Careful... wiper trans can cause damage to anything get pinches.

Latch casket will help. (Assuming all other parts are good too). Any trash/leaves/etc falls in the latch, can work into heater inlet.
Whole leaves above means need a gasket or trim under windshield has issues.

Yes, I've clean mine once last month any not much really found... And old house had Maple next to driveway.
See http://www.fiero.nl/forum/F...HTML/123258.html#p10

Just look into heater resistor opening... A mirror will help. A piece of bent wire will move the junk and vacuum can suck it up.
