Heated front seats not working (1994 850 T5)

Default Heated front seats not working (1994 850 T5)

Hi everyone,

Now that the colder weather is here I have had cause to use my heated seats for the first time since purchasing the car (1994 850 T-5 saloon).

Problem is this.....activating the switch for either front seat seems to have absolutely no effect. The orange light illuminates in the switch but no heat in the cushion at all.

I have owned a variety of Volvo and had one seat heater fail in the past (thermostat), but never known both to not work. I have checked the fuse covering the operation of the seat heaters but all appears to be in order.

Any suggestions or fixes (and estimate of any cost involved?).....all would be much appreciated.

Thanks.

Three things usually cause this:
1. Disconnected wire under the seats due to kids or mechanics, or broken wire due to shoving the seat back and forth a few thousand times.

2. Relay busted - a few quid.

3. Heater element busted - have to be replaced by garage, not cheaply.

Let's hope it's no. 1

Usual cause is broken (red) wire under seat.

There are no relays so discount that.

Heater elements can be a DIY job if your brave, there are two elements one in the seat and one in the back rest.

Brain fade - meant thermostat, not relay.

Sorry.

The drivers heated seat did not work in my 850 a wire had come off the thermostat (underneath the middle of the seat).

Hi all,

Just want to thank everyone who has posted replies above so far.....all advice much appreciated.

I have had the car in at a dealer and they are saying it is most likely the thermostat(s).

Armed with above advice I was keem to explore the possibility of the wiring underneath being damaged, however they said they could not diagnose this - seemed odd that they could not. I imagine that the thermostat is a fairly pricey item and would be expensive to fit....am I right?

Perhaps I am getting cynical, but I suspect the dealer would rather chare for the thermostat work than a simple wiring job....

In any case, if the wire is indeed damaged is this a job easily tackled by and auto electrician etc?

Again, any further advice would be much appreciated. Thanks guys.
Regards,
Duncan

Hi,

mine don't work either (both sides) on my 850se. I've just had the car inspected by the AA (different story) and one of the things he noted was that the wires on the heated seat were broken. He used to work for Volvo and said that it was a common thing.

He also said that the seat works at any teperature below 14 degrees Celcius when you switch it on and that it automaticaly switches off when it reaches a pre-determined temp.

I'd go with the broken wire theory myself :)

Hope you get it sorted,

Andy

Thanks to everyone again for your posts.

Ken...I have read your main post and your reply here....sounds awful! I hope you have some joy with your insurers/AA/Volvo. Will be interested to read the updates.

As per the fault with my heated seats......dealer diagnosed loose wire on passenger seat and new seat base element needed for drivers side. Quoting a ost of about £96 to rectify....

I am guessing this is a Volvo supply only part and requires a fair bit of labour to fit....so the total price is likely to be even more. Anybody have any thoughts on this?

Have a great day all.

Regards,
Duncan

Armed with the information you should be able to find out if an auto electrician or independent volvo garage could fix the problem.
Personally I would go through the yellow pages first.

Hope your days are filled with inexpensive warm bottoms!!!
