Rear A/C Blower Motor

Yahoo Message Number: 100017
Just noticed the rear a/c continually changes about every 15 to 20 seconds from low speed to high speed (back and forth) while set on auto. Front a/c seems okay. Any suggestions or ideas what may be going on with the rear a/c? Thank you!

Is it changing speed or is the compressor kicking off and on?  We had this and the capacitor was bad.

It's changing speed from low to high. Is that what yours was doing when you changed out the capacitor? Did you change out the capacitor or have it serviced - just trying to locate it and see if it is a repair I can do, or if I need it serviced. Thanks!

Normally the capacitor is to start the motor only, not manage speed.

Depending on the type of your AC, there could be two capacitors; one start, the other run; easy check after removing the cover. Make sure to discharge before touching! If it starts, the start cap is probably ok, but possibly the run cap may be faulty; Had this similar problem twice. First time it was the capacitor, the second time, it was a combination of the thermostat and the sensors. Make sure to blow out the sensors of any dust, etc that could be affecting them and also do a hard restart on the thermostat. Mine was solved by doing both and eventually changing the thermo sensors between zones. Hope this helps, Roger Harper

Where are the sensors that I should blow out, and how do you perform a hard start on the thermostat? Mine is an older thermostat with the 4 button model (fan, mode, up, down). Appreciate your assistance!

Compressors usually have both start capacitors and run capacitors coupled with a potential relay, fan motors usually have just run capacitors. They are inexpensive and can be purchased at Grangers online

Btw a start capacitor is usually cylindrical in shape and a run capacitor is oval in shape

Mine wasn't changing speed.  I could hear the compressor try to run for a little bit and then stop and then try to start again.

The sensors on my Intrigue and Affinity (3) since I had three ACs are really thermistors. They are the temp sensors which signal the thermostat/AC/Heat. Usually they are (actually the thermistor) under about 3/4-1" semicircle plastic, slotted round cap. Look around your unit. One is usually under the stereo cabinet (poor location) and these are the sensors for the thermostat. To do a hard restart. Take the thermostat off the wall; unplug it, wait about 2 minutes and reconnect. Or, you can just take out the battery and wait 2 minutes, but disconnecting it worked better for me. I replaced my capacitors in both coaches several times, but if you're unfamiliar with them, then perhaps a tech would be the better choice, Roger Harper

Please excuse me for stealing this thread.  Yahoo decide to cancel my account and thus, I can't send things directly.  Hopefully this will work.
 I am looking for some help with Good Sam "Breakdown" coverage as follows:

Has anyone actually had experience with the God Sam "extended warranty" plan (which name they refuse to use, apparently to differentiate it from others)?  My Easy Care policy is about to expire and the want $8,500 to renew for 3 years.  Before "going naked" (which I'm inclined to do, I though I would check to see if anyone had a good or bad experience with Good Sam.
 They are marketing it like crazy and have quoted me $1,200/year for 3 years, cancelable at any time.  But, I worry about "pre-existing conditions" (sound familiar?) and the whole concept of "breakdown".

Thanks for any ideas.

A friend of ours with a Coachman that was built in 2003 has had  a Good Sam Plan the entire time and has to use it quite regularly. The last time he lost some universal joints and the place he was told to take the the coach did not repair it right, so he had to be towed again for repairs.  Then when he got home he found out his anti lock break system had been compromised.  Fortunately his Regular coach insurance paid for the braking issue.  BUt he had to go to the VP of Good Sam again to get his money for the initial repairs and the follow up repairs, and they only paid for repairs as determined by their own pay schedule.  Fortunately we live where labor rates are low.  When he had transmission issues in the Northwest he came out on the short end, by a big margin.  But the key to this story is he had to develop a personal relationship with the VP of Good Sam to get satisfactory service.  You'll need to have money in the Bank anyway to pay the bills up front and hope you get reimbursed within the following 180 days.  Its tough to keep $25,000+ in the bank for unforeseen coach repairs.  But  you might have, too.  Between losing a radiator and Charge air cooler , throwing a magnet on my genset and having to replace a set of tires, I was out  $18,000 + one summer.  The next year it was an air conditioner, hydraulic  & transmission hoses  and a new fan controller.  This year was HWH slide room bearings. I got off easy.    Repairs are cyclic in nature.  Next year I can see replacing the rear air, up dating the TV's, etc.    Don't skimp on  maintenance, having a sharp tech can pre-emp big repairs.    TWI 2004 intrigue 11731
