BillyJ Posted January 20, 2006 Share Posted January 20, 2006 Yesterday, I was driving my '90 when the Service A/C light came on for a minute or two (in Florida). The A/C works fine. When I run it down all the way the air is very cold. I tried going into the diagnostic mode (OFF and TEMP UP buttons) and this is what cycled through: No E code, 64464,64824,65524,Ec?. I tried the forum SEARCH, but can't decipher the codes. Any ideas? Thanks.BJ Link to comment Share on other sites More sharing options...
Reatta45 Posted January 21, 2006 Share Posted January 21, 2006 No need to over complicate things? Just service A/C, start with a simple A/C pressure check. I would guess you are low on refrigerant, but the gauges will tell exactly. KennyV. Link to comment Share on other sites More sharing options...
Jim Posted January 21, 2006 Share Posted January 21, 2006 You were simply reading wrong what you saw. 64464 was actually B446H Low Refrigerant---- History 64824 is actually B482H ABS brake pressure problem-----History65524 is actually B552H BCM keep alive memory error----HistoryWhat that means is at one time these codes were present but not now, nothing to worry about.

manikmekanik Posted January 23, 2006 Share Posted January 23, 2006 Enter diagnostics and select BCM, page thru to "clear bcm codes" to eliminate the history codes. Exit diags.Re-enter diags to check for new current codes, if none, no problems. Exit diags. Link to comment Share on other sites More sharing options...
Guest tomt Posted January 24, 2006 Share Posted January 24, 2006 My A/C is fine and recently converted and charged. In spite of this, when I go through that first cold period going into winter, and when I first start to use A/C in late spring, I get the same message that you got. It will sometimes be pesky, but then it stops. Others seem to have similar problems during this time period.My mom lives in Sarasota, and commented last week that it had been extremely cold. Check your codes as it's easy, but I'm thinking that the problem relates to an unusual weather change that you have had. Link to comment Share on other sites More sharing options...
