pmercado Posted July 19, 2005 Share Posted July 19, 2005 Hi everyone, I have a 95 Pathy and every time I use the AC my passenger side floor gets flooded. I've traced the drips coming from the square "black box" underneath the glove box. I noticed that I have condensation around the whole box and the spongy gasket on the right front-side of the black box is soaking wet. Can anyone tell me what this black box houses and if I need to replace this whole unit. Also there is a rubber hose connection between this black box and cylinder to the right. Anyone know what this cylider is? I noticed I had lots of water in this connection tube. Then of all days, my fan stopped working today. For the past couple of months the fan only worked in the high position, but today no fan at all. Anyone think this is a switch problem or more likely a dead fan? thanks, pm Link to comment Share on other sites More sharing options...
Animal Posted July 19, 2005 Share Posted July 19, 2005 The black box is the evaporator. The condensation is normal, but should drain to the outside through a tube in the bottom. It's probably just clogged. Try clearing it from the outside with a piece of flexible wire. Link to comment Share on other sites More sharing options...
GrimGreg Posted July 19, 2005 Share Posted July 19, 2005 I agree, clogged drain, look for a 1/4" black plastic tube comming out of the firewall just below the heater hoses. Link to comment Share on other sites More sharing options...
dnodog Posted July 20, 2005 Share Posted July 20, 2005 yep clogged drain i get that all the time. Also try disconneting the tube on the inside{ have somethin to catch the water and clean out that part as well. Link to comment Share on other sites More sharing options...
pmercado Posted July 20, 2005 Author Share Posted July 20, 2005 Thanks guys !!! I blew out the hose from the inside using an air compressor. After reattaching the hose, a quart of water drained out. Now for problem with the fan; I took the console apart and exposed the environmental assembly. I took the fan switch apart from the bottom of the assembly and springs popped out with the mechanical copper contacts to my surprise. I don't think the switch is the problem since it is a mechanical switch, not electrical. I will polish the copper connections though and put it back together tomorrow. I have a feeling it is the fan motor. Any ideas where I should look for this fan? Link to comment Share on other sites More sharing options...
GrimGreg Posted July 20, 2005 Share Posted July 20, 2005 After mine flooded the first time it had sloshed over into the fan and the fan was making horrible noises. I removed the fan, disassembled it, cleaned it , lubed the friction areas and put it back in no troubles. As for the switch, it's not mechanical if it has electrical contacts.

88pathoffroad Posted July 20, 2005 Share Posted July 20, 2005 How so, Greg? If it physically turns to a new position to touch a new contact surface, it should be regarded as mechanical, right? Link to comment Share on other sites More sharing options...
RedPath88 Posted July 20, 2005 Share Posted July 20, 2005 How so, Greg? If it physically turns to a new position to touch a new contact surface, it should be regarded as mechanical, right? That has long been the way I have seen it too... ??? Link to comment Share on other sites More sharing options...
k9sar Posted July 20, 2005 Share Posted July 20, 2005 while you have it apart, be sure to clean out your tray so your drain tube doesn't reclog with the crap you blew out. Link to comment Share on other sites More sharing options...
GrimGreg Posted July 20, 2005 Share Posted July 20, 2005 How so, Greg? If it physically turns to a new position to touch a new contact surface, it should be regarded as mechanical, right? Well since part of it is making and physically switching electrical contact.... I'm thinking mechanical as in like mine which have a cable and lever.

pmercado Posted July 22, 2005 Author Share Posted July 22, 2005 k9sar, thanks for the tip to clean out the evaporator box. I was not successful in fully removing the bottom half of the evaporator tray, since there seems to be a clip or screw which I could not get to in the rear. I was however able to crack it open enough after removing the blower fan resistor assembly. Sure enough I had a bunch of small dried leaves in there which would have clogged the hose again. I guess it gets through the outside vent and gets chopped up by the blower fan wheel. Now as for my fan only operating at high speed, I read a posting on ebay (by a guy trying to sell his blower fan resistor) that says the resistor is my problem. When I took the resistor out it was all rusted, so this is plausible. I ordered a new resistor from for $12, but shipping was $8. It was worth the shipping cost to not go hunting around at various autopart stores. Wish I knew this before I took the blower motor out and accidently broke several of the blades on blower wheel. When I installed the motor back and tested it out, as I suspected the missing blades would cause an unbalanced rotation at high speeds and cause lots of noise. This blower wheel does not seem to be a readily available product, so I requested a part search at UsedPartsLiveAutoRock On another note, I have collected lots of auto parts links for my pathy. Do you think it is a good idea to start a thread for just web links? Link to comment Share on other sites More sharing options...
Precise1 Posted July 22, 2005 Share Posted July 22, 2005 No harm in it.... Go ahead and start it, lets see what turns up. It might be worth pinning in the garage. Lets try not to have a lot of repeats though... B Link to comment Share on other sites More sharing options...
GrimGreg Posted July 22, 2005 Share Posted July 22, 2005 A good list of part links would be cool, maybe we could even start to keep a list with rattings from people who have used certain ones somewhere. Link to comment Share on other sites More sharing options...

This blower wheel does not seem to be a readily available product, ... While you are waiting to find the part, it should be possible to rebalance the blower by removing fins opposite the broken ones. It won't be as effecient and may be a bit louder, due to turbulence, but you should get some cold air without wearing out the bearings in your motor.

pmercado Posted July 23, 2005 Author Share Posted July 23, 2005 I was able to epoxy the several of the blades, so I am now only missing 2. I'll test it out and clip the opposite blades as you suggest if needed. Here is web link thread I started in the garage section: here Let me know what you guys think.
