My a/c does not seem to blow hard ,is there a fix or a upgrade blower motor? The fan speed switch is working fine.

 

If your a/c is anything like mine, the problem isn't the blower motor, it's the power getting to it. If I run a wire from the + side of my battery directly to the blower motor, it blows alot harder than on hi the normal way. I'm thinking it may be the contacts in the blower switch. I just haven't had time to fool with it. Also, since you have a/c, do you have a problem with the a/c holding in water until you shut it off and then all the water drains out at once?

 

My old man was having a similar issue with his '86 Ram. He opened the evaporator case and it was so filthy you could barely see the fins on the evaporator. He cleaned it up and it blows hard now. I did the same on my '99.

 

Did he have to completely tear apart the dash to get into it?

 

I just replaced my heater core that is inside the evaporator case. You have to remove the lower dash supports but the dash itself stays in place. The biggest problem is that you have to brake the A/C freon lines to remove the case. My truck has been garaged most of its life but still had a load of gunk inside the case.

 

I may be wrong, but I could've sworn he told me the evaporator was out under the hood on his '86. And he didn't open the A/C system.

 

I'm afraid to open up my system. It works great I just have the issue of it filling up with water until I either turn the blower to low or shut it off completely. Then the water just gushes out. Before I got it it spent a few years parked under a tree so every time I turned the a/c on you could hear leaves rustling around inside of it until eventually they all shot out of it. I took off the blower motor one day and shot my garden hose in there a few times, that's as much as I'll venture into it for now. Maybe in December when it's not 90+ every day so I could afford to go a couple days without a/c if I had to.

 

Early models had a case that split in half with a front and back. Later models have a body (bottom and sides) and a top that comes off. I have never removed the earlier unit and so I am not sure about what is involved but the 89 I have done. I do not know what year they transitioned but 87 was when most of the changes were made.

 

I just enjoy being able to tell people that my 20+ yr old truck has factory a/c that works great. People assume that 1) it's old and 2) it's a truck so wow it must be hot in the summer with no a/c.

 

I know what you mean 89ram150, it is just a sense of pride. Living on top of the mountain where I do I don't use the A/C much but it will still make you wish for a sweater if you leave it on high. I bought a 20 LB cylinder of R-12 back when they started to talk about doing away with it and I still have enough left for a few more charges if necessary.
