Replying to: breezi (Apr 17, 2009 3:25 am) I have had a car in the past that had the A/C compressor freeze up so that is possible... I've not had your second problem with with my Safari... I did have to replace a blown serpentine belt at around 80,000 miles tho... |

The heater produces heat and also cool air when in the AC mode. Problem is the fan/blower only works in the first two positions. When I turn the control to the high setting there is no response. If I leave the control setting there the fan will come on every once in a while but not stay on steady. Everything works fine in the low and medium settings. The rear heater and AC fan works fine. Cany anyone suggest what may be a solution to my problem.

| hi i have a 1998 astro awd with f&r air and heat. today i had the air on high setting, and the blower motor started making a humming sound. i know i have or had a mouse in the interior of the van but i dont think that would cause the blower motor to hum. is it on its way out or is there a way to tighten up the blower motor up. also the rear air does not blow, the rear heat blows (cold) so i know it is not the motor, i think it is the switch because i pulled the switch away from the dash and and if you juggle and twist it around enough it comes on. any ideas on eather one of the problems would be greatly appricated, i don't want to have to take it to the mechanic for things i can do my self. thank you in advance | |
02 Astro. Has about 75000 miles on it. After a car wash the fan stopped working unless you opened the hood and tapped on the blow motor housing or slammed the door really hard. What could this be? Is it the resitor? How do I get to anything in there? I'll keep searching but it's getting really hot outside and I don't want to put the new baby girl in the hot van at all! Help!!!!

Hi everyone, I was lucky enough to find this forum online and I must say that this has been an extensive discussion into the chevy vacuum line issue. I am very familiar with this as I have run into this problem twice now with my 97 chevy astro and each time I have replaced the lines myself with lines that I have made, and it has worked great. However, I seem to be having a little issue that I wanted to run by everyone. The problem started when I had an issue with the car jumping/shaking while idle. So I took it to the Chevy dealer for an inspection and they told me the Fuel Injector/Spark Plugs/ Distributor Cap, Rotor, and Spark Plug Wires as well as Engine Oil Pressure Sensor was bad. They wanted to charge me $1,900 and I was like h*** no, and so they gave me the car and i went out and bought the parts for $350 and I did the job myself and it works great now. However, when I got it back from the dealer after the inspection, the air was not coming out of any of the vents on any setting. The suspect area is the 3 way adapter behind the accumulator where the vacuum line connects in from the intake manifold. The vaccum line was fine, but the problem is there are now only two tubes connected to that adapter. The first one is the vaccum line from the intake and the second one is another tube that is a little to the left on the accumulator on the firewall. However, the third port is open and there is suction on it. The issue is that I don't remember from when I was fixing the vacuum tube if there is a thrid line that is supposed to connect there. What I did was I put a vacuum cap on that open side of the connector and so the air comes out now and works,, but it doesn't come out as stong as it used to be before I gave the car to the dealer. I was wondering if anyone has any idea about that. I would really appreciate it! Also, the line that is coming out of the firewall is worn out and crumbling and I wanted to get that replaced, but I don't know where that goes into. Basem D. |
