I am new to the boards. Background story:
I moved from California to Miami for school. I shipped my parent's 1996 Toyota Camry here. As I was dropping the car off to the lot where the truck picks up the cars, I turned on the AC because it was pretty hot at the time. I then notice there was no cold air blowing! I asked my mom if she knew about the problem and she said yes. I asked her why didn't she tell me earlier so I can get it fixed! Anyways, I am in Miami and it's been almost 2 or 3 weeks. I can't stand not having AC in this city. It is so hot and humid. I really want to get the AC fixed but my school schedule is really hectic with a lot of tests and quizzes, and I'm in class most of the day. I have to drive 30-40 mins each way to and back from school. I thought I would be ok not fixing the AC and just rolling my window down but after a few weeks it's unbearable. I wanted to bring the car to a shop to fix it, but that is almost impossible because of my class schedule and not being able to take the bus (the bus is 1 hour + and goes through sketchy areas). I could rent a car but the shop said it might take a couple of days and I don't have money to rent a car and get it fixed. So I want to tackle the problem on my own. I am a decent car guy and I've done a lot of DIY on my own car, oil changes, brake replacements, alternator replacements, exhaust replacement, shock/spring replacements, and a few other jobs. Though the AC system looks like the hardest to work on without the proper tools.
as I've stated in the title, the fan blows fine, just the air that comes out is not cold. It doesn't start cold and then gets warm, it just doesn't blow out cold air. I noticed the RPM of the car does rise after I press the AC button (Does that tell me anything).
I got my hands on a AC system book for the 1996 Camry. There is a troubleshoot part and I am going to try and follow that to find the problem.
The first step is to check the AC Fuse. I see the location of the fuse/relay boxes, and but I am not 100% sure where the AC fuse is located. There is the Junction Block No. 1 on the left of the steering wheel, relay block in the inside and near the batteries. In the book, it says the Fuse for the A/C is a 1OA fuse at relay block #4 on the passenger right side of the car. How do I check if the fuse is good or not? and where can I buy another fuse if it's not good?
Thank you so much for reading this long post, and I will update as I go, thanks.
update #1: Wow that is a hard place to reach. I got the panel open, and the fuse is sitting in a pretty hard place to reach. I was hoping it was the fuse but it's not. For reference, the Camry comes with a tweezer and extra fuses in the fuse box cover next to the battery. The fuse looked good, the metal connection was in place. Next step...the AC clutch relay.
I'm not sure how to test the relay, do I need a tester thing? what exactly do I need? and how do I test it. There are 4 relays (from my book) , and do I just put the tester between 1-4, 3-5 terminals? What do they mean when it says apply 6+ between terminals 1 and 4, and apply B+ between terminals 1 and 4? Thanks.
update #2, ok google is awesome. I think I need a multimeter, and put the leads to where the manual tells me to. One question is, for the test that needs the positive battery source (12V) i'm assuming, what's the easiest and best way and safest way to provide that source of battery?
update #3: Just realized, if my fans are working fine, can I replace one of the fan relays and put it in the magnetic clutch relay and see if it works?
update #4: Ok tomorrow I am going to replace relay #3 with the magnetic clutch relay and see if that works. From the manual, it looks like the test is the same for those two relays and if htey look identical, I will just switch it. I will also check the sight glass between radiator and bumper to see if there are bubbles after I run the A/C for a few minutes on high. If I see bubbles, or even if I don't, I think i am getting a a/c recharge kit with pressure guage and leak dye. I will report back tomorrow.
